A chemist fills a reaction vessel with 5.97 atm chlorine (Cl,) gas, 6.65 atm phosphorus (P.) gas, and 1.79 atm phosphorus trichloride (PCI,) gas at a temperature of 25.0°C. Under these conditions, calculate the reaction free energy AG for the following chemical reaction: 6Cl,(g) + P,(g) → 4PCI, (g) Use the thermodynamic information in the ALEKS Data tab. Round your answer to the nearest kilojoule.
Transcribed: A chemist fills a reaction vessel with 5.97 atm chlorine (Cl,) gas, 6.65 atm phosphorus (P gas, and 1.79 atm phosphorus tríchloride (PCI,) gas at a temperature of 25.0°C. Under these conditions, calculate the reaction free energy AG for the following chemical reaction: 6Cl,(2) + P,(g) = 4PCI, (3) Use the thermodynamic information in the ALEKS Data tab. Round your answer to the nearest kilojoule. -1107|1J

Answer

∆G for reaction can be calculated using formula 

∆G = ∆G° + RTlnQ

So, first we need to calculate ∆G° ( standard Gibbs free energy change ) using standard thermodynamic data . 

And Q ( reaction quotient ) using given pressures of each gas .
