Write down the Arrhenius equation relating the rate constant of reaction with temperature , mentioning what the terms indicate.
If `k_(1) and k_(2)` be the rate constant of a reaction at temperature `t_(1)^(@)C and t_(2)^(@)C` , respectively, find out the relation between `k_(1) ,k_(2) and t_(1) and t_(2)` . Given that the activation energy `(E_(a))` of the reaction remains unchanged within the temperature range mentioned.
The rate constant of a reaction at 400K and 500K are `0.02s^(-1) and 0.08s^(-1)` respectively . Determine the activation energy `(E_(a))` of the reaction.
