Essay about Rates of Reactionsin Marble Chips Investigation - Rates of Reactionsin Marble Chips Investigation Aim The aim of this experiment is to discover how the rate of reaction between Marble chips and Hydrochloric acid changes as the concentration of the acid is increased or decreased.

#

The rate of reaction of magnesium with hydrochloric acid

#

I think that my results are good as I was expecting a few more anomalous results, but I only got one.

Chemistry Rates Of Reaction Marble chips and Hydrochloric acid

#

Throughout the experiment I encountered some problems which I have changed to make my final experiment more successful and reliable.

#

Rate of Reaction Between Marble Chips and Dilute Hydrochloric Acid

#

I think this has occurred because of the following reason:

#

#

The variability of a measurement cannot be determined from a single measurement, therefore multiple measurements….

#

#

Preliminary For my preliminary work I decided to find out how long it would take for different concentrations to fill up to 10cm of hydrogen. To find a rate of reaction you measure the amount of product given off by the reaction in a unit of time

#

#

I also said the lower the concentration the slower the rate, and my results show this aswell.

#

#

Therefore leading on to my other graph this shows that as the strength of the concentration increases so does the rate of reaction. You do not have JavaScript enabled.

In the graph of average times the lowest concentration took 48, 85 seconds, in my highest concentration the time was 9. Essay on Rate of Reaction Between Marble Chips and Dilute Hydrochloric Acid - An investigation into how changing one variable influences the rate of reaction between marble chips and dilute Hydrochloric acid Planning Section Rare dilute hydrochloric acid reacts with marble chips the following reactions occurs:

#

Acid and the marble chips. In Search of Solutions:

#

#

From my background I knowledge I can explain why the arte of reaction increased as the strength of the concentration did. There are not many collisions collision between particles from the Between the particles from the acid and marble chips is frequent.

#

In my results I found that there was too much of a gap between concentration o. Could you do any further work to get more evidence?

#

#

Enzymes are biological catalysts, which speed up the rate of reaction without being used up during the reaction, which take place in living organisms. There are many variables that affect the rate of this reaction such as the following:

#

#

I also predict that the more dilute the acid is the more water there is with the acid the slower the chemical reaction. The solution becomes increasingly difficult to see through as more and more sulphur is formed.

#

#

Description Magnesium reacts with dilute hydrochloric acid in a conical flask which is connected to an inverted measuring cylinder in a trough of water. I also predicted that the increase of concentration would quicken the time for the reaction to take place.

#

#

This is because if you increase the concentration there are more particles to react with the marble chips, so this is going hydrofhloric increase the rate.

#

#

So I decided to u se a gas burette instead as it showed our results to one decimal place. Pour the acid into the cm 3 conical flask.

#

Below are the following results I got for my preliminary experiment.

#

Is milligrams bigger or grams? I didn't do the last type of concentrations because I knew that they resction be a reaction because water doesn't react with Marble chips.

#

You can see that the highest concentration of acid, which is 50 Cm3, has the fastest rate of reaction.

#

Throughout the experiment I encountered some problems which I have changed to make my final experiment more successful and reliable. Were my results accurate?

#

Solids, liquids and gases. To do this, I will change the concentration of the HCl and measure how that affects the amount of CO2 produced during the reaction, and hence, find the rate.

In the concentration 2, I first recorded The increase of concentration makes the likely hood of two particles colliding higher.

I think that I could use a different variable, such as temperature, or surface area etc. Because the time it takes produces CO increases with the higher concentration of HCL, this means that that the higher concentration is reacting faster with the marble chips. If the solutions is made more concentrated it means there are more particles of acid colliding with water molecules. Get feedback on grammar, clarity, concision and logic instantly. The HCL particles will have enough activation energy to collide with the marble chips; the activation energy will loosen the particles and enable new bonds to from so the reaction can take place.

Every reaction requires a different amount of energy to create the reaction, which is called the activation energy; when there is not enough…. Ensure that there are no naked flames.

A list of variables, which I will attempt to keep the same Surface Area: Could you do any further work to get more evidence? In the higher concentration there will be more HCL particles to have a successful collision with calcium carbonate marble chips loosening the bonds and forming new ones. Single-holed rubber bung and delivery tube to fit conical flask Note 1.

The rate of the reaction affects how quickly the CO2 is produced.
