Solution

The correct option is A 45 kJ/mol
In a reaction the potential energy of the reactants is 40 kJ/mol, the potential energy of the products i 10 kJ/mol and the potential energy of the activated complex is 55 kJ/mol. What is the activation energy for the reverse reaction?
A
45 kJ/mol
The activation energy for the reverse reaction is the difference between the potential energy of the activated complex and the potential energy of the product of forward reaction. It is
$55 - 10 = 45 k J / m o l$
