Consider the following reaction:
CO2(g)+CCl4(g)⇌2COCl2(g)
Calculate ΔG for this reaction at 25 ∘C under these conditions:
PCO2PCCl4PCOCl2===0.140atm0.185atm0.745atm
ΔG∘f for CO2(g) is − 394.4 kJ/mol , ΔG∘f for CCl4(g) is − 62.3 kJ/mol , and ΔG∘f for COCl2(g) is − 204.9 kJ/mol .
Express the energy change in kilojoules per mole to three significant figures.
