For the reaction NO + O2 = NO2, what would happen to the this reaction if we assume that the KC is greater than Qc?

Answer 1

If the reaction quotient Qc is less than the equilibrium constant KC, then the reaction is not at equilibrium and will proceed in the forward direction to reach equilibrium. In this case, the concentrations of the reactants NO and O2 would decrease, while the concentration of the product NO2 would increase until Qc is equal to KC. This means that the reaction would favor the formation of more NO2 until equilibrium is reached.
