In the decomposition of H2O2 at 300K, the energy of activation was found to be 18 kcal/mol while it decreases to 6kcal/mol when the decomposition was carried out in the presence of a catalyst at 300k. How many times is the catalysed reaction faster than the uncatalyased one?
K = Ae-E/RT (E is activation energy)
rate(R)= K(a)n (k=rate constant & a is concentration , n is order of reaction)
rate directily proportional to rate constant so
R1/R2 = K1/K2 = e[-E1+E2]/RT
R1/R2 = e[-18+6]/RT (R=.08321units , T=300)
=e-[0.5] (e=2.8 )
R2 = 1.67R1 (approx)
