Consider the reaction.

The rate constant for two parallel reactions were found to be `10^(-2) dm^(-2)mol^(-1)s^(-1)` and `4xx10^(-2)dm^(-3)mol^(-1)s^(-1)` . If the corresponding energies of activation of the parallel reaction are 100 and 120 kJ/mol respectively, what is the net energy of activation `(E_(a))` of A

Options

A. 100 kJ/mol
B. 120 kJ/mol
C. 116 kJ/mol
D. 220 kJ/mol

Answer

C
