Calculate the change in enthalpy (ΔH) for the combustion of methane gas (CH4) at 25°C and constant pressure of 1 atm. The equation for the combustion of methane is:CH4 (g) + 2O2 (g) → CO2 (g) + 2H2O (l) Given the standard enthalpies of formation at 25°C are:ΔHf[CH4 (g)] = -74.87 kJ/mol ΔHf[CO2 (g)] = -393.5 kJ/mol ΔHf[H2O (l)] = -285.8 kJ/mol Assume that water is in its liquid phase at the end of the reaction.

A chemistry student is conducting an experiment in a closed container where nitrogen dioxide is being converted into nitrogen oxide and oxygen gas. If the student increases the concentration of the nitrogen dioxide in the container, how will it affect the equilibrium position of the reaction and what can be done to restore the equilibrium position? Use Le Chatelier's principle to explain your answer.
