Question

Why does an increase in temperature result in an increase in reaction rate?

Answer 1

When we increase the temperature in a chemical reaction, this increases the particles kinetic energy, making them move much faster than they were before. This also increases collision between the particles and the rate of reaction.

Answer 2

An increase in temperature typically increases the rate of reaction. An increase in temperature will raise the average kinetic energy of the reactant molecules. Therefore, a greater proportion of molecules will have the minimum energy necessary for an effective collision.
