Consider the following elementary reaction: 2NO(g) → N2O2(g)

Suppose we let k1 stand for the rate constant for this reaction, and k-1 stand for the rate constant of the reverse reaction. Write the expression that gives the equilibrium concentration of NO in terms of k1, k-1. And the equilibrium concentration of N2O2.

Explanation:

Hello!

In this case, since the reaction may be assumed in chemical equilibrium, we can write up the rate law as shown below:

However, since the rate of reaction at equilibrium is zero, due to the fact that the concentrations remains the same, we can write:

Which can be also written as:

Then, we solve for the concentration of NO to obtain:
