Reaction Mechanisms

Postby Kate_Santoso_4F » Sun Mar 10, 2019 10:07 pm

Consider the conversion of C to D via a one-step mechanism. The activation energy of this conversion is 3 kcal/mol. The energy difference between D and the transition state of the reaction is 7 kcal.mol. Calculate delta H for the reaction C --> D.
Could someone please explain how to do this problem?

It may help to draw a reaction profile using the given information. Remember that you are looking for the overall difference between reactants and products.

I would assume you use the energy of products minus energy of reactants because delta H is a state property not a kinetic property, so therefore the activation energy is not concerned in that aspect.
