graph can be found here http://brainly.com/question/71237
a) Does the graph represent an endothermic or exothermic reaction?

b) Determine the heat of reaction, ∆H, for this reaction.

c) Determine the activation energy, Ea, for this reaction.
(Points : 6)

Answer 1

I think its an endothermic graph but I don't know how to find b or c help would be greatly appreciated just explain it and show me how to do it

Answer 2

Heat of the reaction is the difference between the energy of reactants and the products. A+B are the reactants and C+D are the products. So locate and subtract their energies.

Answer 3

Activation energy is the energy of the transition state minus energy of the reactants. Transition state is at the peak of the curve.

Answer 4

Also, this is a curve for an exothermic reaction. Because the energy of products is less than the energy of reactants.
