1ans (B)
Maximum value of rate constant = A (Arrhenius Factor)
also fraction of molecules in activated state = kA = 10-2100
so A = 693/2 ≈ 3.4 * 102
A 1st order reacn with half life 20 days is cccuring at 27°C . If 10-2 % molecules r in activated state . Find the maximum rate constant.
(A) 3.4 * 10-2
(B) 3.4 * 102
(C) 10-4
(D) can't be determined
