Answer:
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
