A chemist fills a reaction vessel with 9.67 atm chlorine (Cl₂) gas, 9.63 atm phosphorus (P4) gas, and 4.08 atm phosphorus trichloride (PC13) gas at a temperature of 25.0°C. Under these conditions, calculate the reaction free energy AG for the following chemical reaction: 6 Cl₂ (g)+P4 (g) ⇒ 4PCl3 (g) Use the thermodynamic information in the ALEKS Data tab. Round your answer to the nearest kilojoule.
