Calculate the reaction quotient (Qc) for the chemical equation:2NO(g) + O2(g) ⇌ 2NO2(g)At a certain reaction conditions, the concentrations of NO, O2, and NO2 are 0.45 M, 0.25 M, and 0.60 M respectively. Determine if the reaction is at equilibrium and, if not, in which direction will it proceed to reach equilibrium.
