How Concentration and Temperature Affects the Rate of Reaction

How Concentration and Temperature Affects the Rate of Reaction between Magnesium Ribbon and Hydrochloric Acid.

WHAT I AM INVESTIGATING

I am going to investigate how concentration and temperature affects

the rate of reaction between magnesium ribbon and hydrochloric acid.

MY PREDICTION

The thing which I expect to happen is the more acid added to water the

faster the reaction will happen. Also the hotter the solution the

quicker the reaction will happen.

THEORY TO BACK UP PREDICTION

This will happen because when the temperature increases it will give

the particles energy which will make the particles move quicker

causing more particles to “collide” this will make the reaction

quicker.

I predict that these factors might have an effect on the results

1. Temperature- how hot or cold

2. Concentration- how much acid, how little

3. surface area- how big or small

4. Time- how fast, how slow

5. Catalyst- will speed up the reaction but won’t get used up.

6. mass of magnesium- how much magnesium

The idea that I am going to investigate is how the increase of

temperature will affect the speed of reaction.

Planning

The equipment I will need is:

· Goggles for eye protection

· Beaker to put acid and water in

· Stop clock for measuring the time

· Magnesium strips to put in the solution the magnesium strip will

be 3cm

· Acid to mix with the water

· Water to mix with the acid

· Measuring cylinder to make the experim...
