Activation Energy

If the activation energy increases then does that mean that the reaction rate decreases?

Re: Activation Energy

If activation energy increases, the reaction will be slower since more energy is needed in order for the reaction to occur and the reaction rate would be a larger value.

Re: Activation Energy

The activation energy is the amount of energy required to go from the reactants to the transition state. So, if activation energy increases that results in more energy required, which causes for a slower reaction. A slower reaction means a higher reaction rate.

Re: Activation Energy

Increasing activation energy means that the reaction rate is increasing because you are making the reaction slower and causes more energy to be needed.
