Calculate the reaction quotient, Qc, for the following reaction:2NO2(g) + 7H2(g) → 2NH3(g) + 4H2O(g)at a temperature of 300 K and a pressure of 0.5 atm for each gas species. The equilibrium constants, Kc, at the same temperature and pressure are:Kc = 0.0080 for the reverse reactionKc = 7.2 × 10^-7 for the forward reaction
