Item 28
Part A
Consider the following reaction:
CO2 (g) + CC4 (g)
= 2COC12 (g)
Calculate AG for this reaction at 25 °C under these conditions:
Pco,
0.140 atm
0.165 atm
Pcocl,
0.755 atm
AG for CO2(g) is –394.4 kJ/mol. AG for CC4 (g) is –62.3 kJ/mol, and AG; for COCl2 (g) is – 204.9 kJ/mol.
Express the energy change in kilojoules per mole to one decimal place.
