Activation Energy

Postby Rhea Shah 2F » Sun Mar 15, 2020 11:31 pm

How do you figure out the rate of a reaction based on the graphs of the activation energy?

The higher the activation energy, the lower the reaction rate, as a general rule.

Normally if the activation energy is higher, the reaction rate is slower because it requires more energy.

Catalysts can also be used to affect the activation energy that a reaction needs to proceed by lowering such activation energy. This is independent of the reaction and the catalyst is not consumed in the reaction itself.

If you have a higher activation energy, more energy will be needed to move the products past that activation energy hump, and because you need more energy, you can assume that inorder for the reaction to progress, you are going to need more time to get past that activation energy if it was higher rather than if it was lower. Therefore, the higher the activation energy the lower the rate of the reaction.
