### Effect of temp. on rate constants

Why does raising the temperature of a reaction increase the rate constant of the reaction with the higher activation barrier more than it will the rate constant of of the reaction with the lower energy barrier?

### Re: Effect of temp. on rate constants

If you have something with a really big activation energy, it needs all the help it can get, so raising the temperature will have a substantial effect on increasing the rate. Conversely, if a reaction has already a low activation energy, the rate is occurring quickly already. Raising the temperature is not going to have as big of an effect on rate.
