Question

Given below are two statements : R = 8.314 J K^-1mol^-1 and 1 cal = 4.2 J

Statement I : When Ea = 12.6 kcal/mol, the room temperature rate constant is doubled by a 10°C increase in temperature (298 K to 308 K)

Statement II : For a first order reaction A → B,

Here [A]₀ is the initial concentration of A and t_1/2 is half-life of reaction.

In the light of the above statements, choose the correct answer from the option given below :
