Rates of Reaction

What is the Effect of Raising the Temperature
on the Rate of a Chemical Reaction?

Raising the temperature will increase the rate
of a chemical reaction because

1. Raising the temperature makes the particles move faster.
This means that the particles collide more frequently
with each other and the rate of the reaction increases.

2. The faster the particles are moving, the more energy they
have and the greater is the proportion of them that will have
the required activation energy for the reaction to occur.

The effect of number 2
on the reaction rate is greater than the effect of number 1.

As a general guide, raising the temperature of a reaction
by 10 °C will double the rate of a reaction.
The gradient of the plot will be twice as steep.
