1. CH₄(g) + 2O₂(g) CO₂(g) + 2H₂O(l) Determine the temperature ( in K) such that the reaction is in equilibrium in its standard states

Compound		Hf (kJ mol-1)		S (J mol-1 K-1)
CH4 (g)		-74.87		188.66
O2 (g)		0.00		205.70
CO2 (g)		-393.51		213.74
H2O (l)		-285.83		69.91

2.Consider the chemical reaction and thermochemical information and initial partial pressures of the reaction components given below: Cl₂O(g) + O₂(g) Cl₂(g) + O₃(g)

	Hf (kJ/mol)		S (J mol-1 K-1)		P (atm)
Cl2O	87.86		267.89		0.235
O2	0.00		205.70		0.859
Cl2	0.00		223.08		4.95
O3	142.67		238.92		7.48

Determine G (in kJ) for this reaction at 505.29 K. Assume H_f and S do not vary as a function of temperature. Report your answer to two decimal places
