For the reaction , the rates are defined as , , and . Which of the following is the correct relation — Chemical Kinetics Chemistry Question

💡 Solution & Explanation

The unified rate is $-\frac{1}{2}\frac{d[N_2O_5]}{dt} = \frac{1}{4}\frac{d[NO_2]}{dt} = \frac{d[O_2]}{dt}$. Substituting the rate expressions gives $\frac{k_1}{2} = \frac{k_2}{4} = k_3$. Multiplying by 4 gives $2k_1 = k_2 = 4k_3$.
