Shifting Equilibrium in a NO and O2 Reaction

Medium General Chemistry Chemical Equilibrium

Consider the following equilibrium reaction:

2 NO(g) + O₂(g) ⇌ 2 NO₂(g)

At a certain temperature, the equilibrium constant (K_c) for this reaction is expressed as the ratio of the concentrations of products to reactants at equilibrium:

K_c = [NO₂]² / ([NO]² × [O₂])

If the concentration of NO is doubled while the concentrations of O₂ and NO₂ remain unchanged, which of the following statements is true regarding the system at equilibrium?

The concentration of NO2 will increase.

The equilibrium will shift to the left.

The value of Kc will increase.

The concentrations of all species will become equal.
