An organic compound dissociates into n parallel first order reactions simultaneously and produces n different products P 1 , P 2 , P 3 , ......., P n having rate constants k, 2k, 3k, ......, nk and activation energies E, 2E, 3E ..............., nE respectively. Calculate the overall energy of activation of the compound P.
Text Solution
Verified by ExpertsCHECK THE SOLUTION.
E overall = E/3(2n+1)
E dqy = E/3(2n+1).
Sol. 
K eff = K 1 + K 2 + K 3 + ............................K n
K eff = K + 2K + 3K + ............................nK
= 
diff. with respect to T.
Ea 
E overall = 
= 
= 
= E/3(2n+1)
