Calculate the standard enthalpy change and the standard entropy change for the reaction: 2HCl(g) + Mg(s) → MgCl2(s) + H2(g) Given the following standard enthalpy of formation values: - HCl(g) = -92.31 kJ/mol - MgCl2(s) = -641.8 kJ/mol - H2(g) = 0 kJ/mol - Mg(s) = 0 kJ/mol Also given the following standard molar entropy values:- HCl(g) = 186.9 J/Kmol - MgCl2(s) = 138.53 J/Kmol - H2(g) = 130.7 J/Kmol - Mg(s) = 32.85 J/Kmol

Calculate the reaction quotient (Qc) for the following reaction at 25°C, given the concentration of reactants and products:2NO2(g) + F2(g) ⇌ 2NO2F(g)[NO2] = 0.30 M, [F2] = 0.40 M, [NO2F] = 0.60 M.Is the reaction at equilibrium? If not, in which direction will the reaction proceed to achieve equilibrium?
