We know that for a given reaction when the temperature increases from 100 k to 200 k the rate constant doubles. what is the activation energy in kj/mol

The activation energy of the reaction is 1.152 kJ/mol.

Explanation:

Activation energy is the minimum amount which is absorbed by the reactant molecules to undergo chemical reaction.

Initial temperature of reaction =

Final temperature of reaction =

Initial rate of the reaction at 100 k =

Final rate of the reaction at 200 k =

Activation energy is calculated from the formula:

R = Universal gas constant = 8.314 J/ K mol

the answers would be

the first one and the second one
