If `K_(1)=` Rate constant at temperature `T_(1)` and `k_(2)` rate constant at temperature `T_(2)` for a first order reaction, then which of the following relation is correct ?
A. `log. (k_(2))/(k_(1))=(2.303)/(RT)[(T_(2)-T_(1))/(T_(1)T_(2))]`
B. `log. (k_(2))/(k_(1))=(E_(a))/(2.303RT)[(T_(2)-T_(1))/(T_(1)T_(2))]`
C. `log. (k_(2))/(k_(1))=(E_(a))/(2.303RT)[(T_(1)T_(2))/(T_(2)-T_(1))]`
D. `log. (k_(1))/(k_(2))=(E_(a))/(2.303RT)[(T_(2)T_(2))/(T_(2)-T_(1))]`
