The rate constant for two parallel reactions were found to be 1.0 x 10-2 dm3 mol–1 s-1 and 3.0 x 10-2 dm3 mol–1 s-1. If the corresponding energies of activation of the parallel reactions are 60.0 kJ mol-1 and 70.0 kJ mol-1 respectively, what is the apparent overall energy of activation?
  • a)
    130.0 kJ mol-1
  • b)
    67.5 kJ mol-1
  • c)
    100.0 kJ mol-1
  • d)
    65.0 kJ mol-1
Correct answer is option 'B'. Can you explain this answer?

-1 s-1. The rate equation for the overall reaction is given by:
Rate = k1[A] + k2[B]
where k1 and k2 are the rate constants for the individual reactions, and [A] and [B] are the concentrations of the reactants.

In this case, the rate constant for the first reaction (k1) is not given, so it is impossible to determine the rate equation for the overall reaction.

Hiii Jatin!!! So You can use the formula Eanet=K1Ea1+K2Ea2/K1+K2 you will get the answer 67.5 KJ/mol... Regards
