Two reactions A toProducts and B toProducts, have rate constants k_(A) and k_(B) at temperature T and activation energies E_(a) and E_(b) respectively. If k_(A) gt k_(B) and E_(a) lt E_(b) and assuming that pre-exponential factor (A) for both the reactions is same then

Answer»

at higher temperatures `k_(A)` will be greater than `k_(B)`
at LOWER temperatures `k_(A)` and `k_(B)` will be close to each other in magnitude
as temperature rises `k_(A)` and `k_(B)` will be close to each other in magnitude
at lower temperature `k_(B) GT k_(A)`
