JEE Main•Chemistry•AssertionReason
Q.57. Given below are two statements:R = 8.314 J K⁻¹ mol⁻¹ and 1 cal = 4.2 JStatement I: When $E_a$ = 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 $\rightarrow$ B, [Figure: Graph showing $t_{1/2}$ on y-axis and $[A]_0$/mol L⁻¹ on x-axis, with $t_{1/2}$ decreasing as $[A]_0$ increases.]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:
