Calculate the standard enthalpy of formation of methane (CH4) given the following enthalpy data: C(graphite) + 2H2(g) → CH4(g) ΔH° = -74.8 kJ/mol ΔH°f[C(graphite)] = 0 kJ/molΔH°f[H2(g)] = 0 kJ/mol (Hint: Use Hess's Law and the fact that the standard enthalpy of formation of an element in its most stable state is zero.)

A chemistry student is asked to determine the effect of temperature and pressure on the equilibrium of the reaction: 2NO2(g) ⇋ N2O4(g) using Le Chatelier’s principle. The initial concentration of NO2(g) is 0.5 mol/L and the reaction is carried out at 25°C. How will the equilibrium shift if the temperature is increased to 100°C and the pressure is decreased to 0.5 atm?
