For the elementary reaction: 2 + -> 2, the volume of a container is tripled. The rate becomes — Chemical Kinetics Chemistry Question

💡 Solution & Explanation

For an elementary reaction, rate = K [$NO$]^2 [$O_2$]. Tripling the container volume reduces the concentration of each gas to 1/3 of its initial value. New rate = K * ([$NO$]/3)^2 * ([$O_2$]/3) = 1/27 * K [$NO$]^2 [$O_2$] = 1/27 * initial rate.
