Question

For the reaction \mathrm{A(g) \rightleftharpoons 2B(g)}, the backward reaction rate constant is higher than the forward reaction rate constant by a factor of 2500 at 1000 K. [Given R = 0.0831\ \mathrm{L\,atm\,mol^{-1}\,K^{-1}}.] Kp for the reaction at 1000 K is:

Vishal Gupta · Accepted Answer

C. Kc = \frac{kf}{kb} = \frac{1}{2500} = 4	imes10^{-4}. \Delta ng = 2 - 1 = 1, so Kp = Kc(RT) = 4	imes10^{-4} 	imes 0.0831 	imes 1000 \approx 0.033.
