Calculate the standard enthalpy change for the neutralization reaction between hydrochloric acid (HCl) and sodium hydroxide (NaOH) in aqueous solutions. The balanced chemical equation for the reaction is as follows:HCl(aq) + NaOH(aq) → NaCl(aq) + H2O(l) Given the enthalpy of formation for HCl(aq) is -167.2 kJ/mol, NaOH(aq) is -469.14 kJ/mol, NaCl(aq) is -407.3 kJ/mol, and H2O(l) is -285.83 kJ/mol. The reaction is carried out at standard temperature and pressure.

Calculate the reaction quotient, Qc, for the reaction: 2 NO2 (g) + Cl2 (g) ⇌ 2 NO2Cl (g)At a certain temperature, the concentrations were found to be: [NO2] = 0.15 M, [Cl2] = 0.20 M, and [NO2Cl] = 0.10 M.Is the reaction at equilibrium? If not, which direction would the reaction proceed to reach equilibrium?
