Question

question 1 of 10
what would happen if no were added to n₂(g) + o₂(g) ⇌ 2no(g) at equilibrium?
a. k_eq would decrease.
b. more n₂ and o₂ would form.
c. k_eq would increase.
d. more no would form.

Explanation:

Step1: Recall Le - Chatelier's principle

When a stress is applied to a system at equilibrium, the system will shift to relieve the stress.

Step2: Analyze the addition of NO

Adding NO (a product) to the equilibrium system $N_2(g)+O_2(g)
ightleftharpoons 2NO(g)$ is a stress. The system will shift to the left to consume the added NO.

Step3: Determine the result of the shift

Shifting to the left means more $N_2$ and $O_2$ will be formed. The equilibrium constant $K_{eq}$ only changes with temperature and is not affected by the addition of reactants or products.

Answer:

B. More $N_2$ and $O_2$ would form.
