Calculate the enthalpy change and the entropy change of the reaction where 2 moles of HCl(g) reacts with 1 mole of CaO(s) to produce 1 mole of CaCl2(s) and 1 mole of H2O(l). Given the bond dissociation enthalpies (in kJ/mol) of H-H is 436, Cl-Cl is 243, H-Cl is 431, and O-H is 463. The standard entropies (in J/mol K) of HCl(g) is 186.9, CaO(s) is 38.2, CaCl2(s) is 223.0, and H2O(l) is 69.9.

A student wants to know the equilibrium concentration of hydrogen gas and nitrogen gas at a particular temperature and pressure when they are mixed in a container in a 2:1 ratio. The student also wants to calculate the equilibrium constant of the reaction when nitrogen and hydrogen form ammonia. Can you help the student by designing a step-by-step procedure to find the equilibrium concentrations and equilibrium constant at the given conditions?
