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

Answer»

`In(k_(2))/(k_(1))=(E_(a))/(R)[(1)/(T_(1))-(1)/(T_(2))]`
`In(k_(2))/(k_(1))=(E_(a))/(R)[(1)/(T_(2))-(1)/(T_(1))]`
`In(k_(2))/(k_(1))=(E_(a))/(R)[(1)/(T_(2))+(1)/(T_(1))]`
`In(k_(2))/(k_(1))=(E_(a))/(R)[(1)/(T_(1))+(1)/(T_(2))]`

SOLUTION :According to ARRHENIUS EQUATION `In(k_(2))/(k_(1))=(E_(a))/(R)[(1)/(T_(1))-(1)/(T_(2))]=-(E_(a))/(R)[(1)/(T_(2))-(1)/(T_(1))]`
`In(k_(1))/(k_(2))=-(E_(a))/(R)[(1)/(T_(1))-(1)/(T_(2))]`
