In the reversible reaction, the difference between the activation energy of the foward reaction?

Question

and the activation energy of the reverse reaction is equal to the..

1- potential energy of the product
2 - heat of reaction
3- potential energy of reactents
or 4 - activation complex

thanks, this is a review sheet and im stuck on some of the questions!

Answer 1

2

Answer 2

its choice 2, heat of reastion, also known as delta H. i assume u need to know the picture. if they ask u what delta H or heat of reation is its arrow between the potential energy of the reactants and products

Answer 3

I think its #1 but I'm not completely sure.
