I have been asked to investigate how the temperature of an experiment

affects the rate of reaction. In the experiment I will do it as the

temperature of the hydrochloric acid.

How Does the Temperature Affect the Rate of Reaction?

Introduction

I have been asked to investigate how the temperature of an experiment

affects the rate of reaction. In the experiment I will do it as the

temperature of the hydrochloric acid.

Reaction rates can be explained by the Collision Theory. The rate of

reaction depends on how often and how hard the reacting particles

collide with each other. Basically the particles have to collide in

order to react.

If the temperature is increased, the particles will have more energy

and so will move quicker. If they're moving quicker, they will have

more collisions.

Variables

---------

The variables that may affect my investigation are:

· The temperature

· The size of the pieces of marble chips

· How much hydrochloric acid you use in the flask

The variable that I am going to investigate is the temperature. This

is because there is more of an advantage due to the fact that there is

more of a range of temperature than there is in the size of marble

chips you use or the amount of hydrochloric acid you use.

Prediction

I predict that when I increase the temperature of the experiment, the

reaction will take place faster. This is because when the temperature

increases, the particles will all mov...
