Reaction Profile Intermediate Energy
A reaction proceeds via a two-step mechanism. The first step is rate-determining, with an activation energy of 75 kJ/mol. The second, faster step has an activation energy of 25 kJ/mol. If the enthalpy change for the overall reaction is kJ/mol, what is the energy of the intermediate relative to the reactants?
A
75 kJ/mol higher than reactants
B
50 kJ/mol higher than reactants
C
40 kJ/mol lower than reactants
D
35 kJ/mol higher than reactants
