Consider this equilibrium:
N2(g) + O2(g) 2NO(g).

Nitrogen gas and oxygen gas react when placed in a closed container. As the reaction proceeds towards equilibrium, what happens to the rate of the reverse reaction?
1It increases as the concentration of products decreases.
2It decreases as the concentration of products decreases.
3It increases as the concentration of products increases.
4It decreases as the concentration of products increases.
5It remains constant as the concentration of products remains constant.
