The initial concentration of N2O5 in the first-order reaction N2O5(g) → 2 NO2(g) + 12 O2(g) was 1.2 × 10-2 mol L-1 at 298 K. The concentration of N2O5 after 30 minutes was 0.60 × 10-2 mol L-1. Calculate the rate constant of the reaction at 298 K.

Match List I (Order of reaction) with List II (Unit of rate constant): List I: A. Zero order B. First order C. Second order D. Third order List II: I. mol-1 L s-1 II. mol-2 L2 s-1 III. s-1 IV. mol L-1 s-1 Choose the correct matching:

Given below is an expression for the rate constant of a first order reaction occurring at a certain temperature, T (K): ln k = 14.34 - 1.25 × 104T The energy of activation in kcal mol-1 for the reaction is: (Given: k in s-1, R = 1.987 cal mol-1 K-1)
