Activation energy `(E_(a))` and rate constants (`k_(1)` and `k_(2)`) of a chemical reaction at two different temperatures (`T_(1)` and `T_(2)`) are related by

Options

A. `ln.(k_(2))/(k_(1))=-(E_(a))/(R)((1)/(T_(2))-(1)/(T_(1)))`
B. `ln.(k_(2))/(k_(1))=-(E_(a))/(R)((1)/(T_(2))+(1)/(T_(1)))`
C. `ln.(k_(2))/(k_(1))=(E_(a))/(R)((1)/(T_(1))-(1)/(T_(2)))`
D. `ln.(k_(2))/(k_(2))=-(E_(a))/(R)((1)/(T_(1))-(1)/(T_(2)))`

Answer

A, C

Explanation

Ace. To Arrheneis equation
`ln.(K_(2))/(K_(1))=(E_(a))/(R)[(1)/(T_(1))-(1)/(T_(2))]`
option (1) and (3) are same
