Question
What happens to the rate constant k and activation energy Ea as the temperature of a chemical reaction is increased? Justify.

Solution
As the temperature of a chemical reaction rises, the rate constant k rises and the activation energy Ea falls.
According to Arrhenius equation
k = `"Ae"^(-"E"_"a"//"RT")`
As a result, the rate constant k rises exponentially as the temperature rises.

It is generally observed that the rate of a chemical reaction becomes double with every 10°C rise in temperature. If the generalisation holds true for a reaction in the temperature range of 298 K to 308 K, what would be the value of activation energy (Ea) for the reaction?
Assertion (A): A reaction can have zero activation energy.
Reason (R): The minimum extra amount of energy absorbed by reactant molecules so that their energy becomes equal to the threshold value is called activation energy.
