Identify the correct statement? — Chemical Equilibrium Chemistry Question

💡 Solution & Explanation

The rate constants are defined as k = A e^(-E_a/RT). For the backward reaction, E_a(bwd) = 74.826 kJ/mol = 74826 J/mol. k_b = A e^(-74826 / (8.314 × 300)) = A e^(-74826 / 2494.2) = A e⁻³⁰. Assuming the pre-exponential factor A is conceptually modeled as unity for this analysis, k_b = e⁻³⁰. Therefore, correct answer is D.
