Question
Consider the unbalanced gas-phase equilibrium system below at 25°C.
AH = -173 kJ
The enthalpy change above is calculated when the reaction is balanced
using smallest, whole-number coefficients.
The box below represents a 2.0 liter container of this system at equilibrium, where temperature is 25°C. Each
molecule in the drawing represents one mole of each substance.
2.0 L
Based on your calculated Kc, which is the numercal value and sign (in
kJ/mol) of the standard gibbs Free Energy change, AGO, at 25°C?
-8.17
-31.9
O 8.17
O 31.9
