Question

For the reaction at equilibrium: 2 NO(g) + O2(g) → 2 NO2(g) Which change will increase the amount of NO2(g)? a. Remove NO gas b. Add NO gas c. Add a catalyst d. Remove O2 gas

Answer 1

b. Add NO gas

Step-by-step explanation:

According with Le Chatelier´s principle, when a reactant is added the equilibrium is displaced to the product(s), to achieve the equilibrium again. Therefore, if NO is added in the reaction, it will be produced more of NO2(g).
