# Determine the activation energy for the reverse reaction

Hey ,
I still do not understand how to determine the activation energy for the reverse reaction when you are given the activation energy for the forward reaction and the delta h for the reaction. I was told to draw an energy diagram but I think I am drawing it wrong. I do know that the activation energy for the reverse reaction is larger than the forward reaction. Could someone explain how to get the activation energy and how to properly draw a potential energy diagram.
Thanks

In general $$activation~energy_{forward}~-\Delta H~=~activation~energy_{reverse}$$

I think that your text will be better for understanding the potential energy diagram, it is quite essential that you understand the diagram.
