Consider the reaction:
I2(g) + Cl2(g) 2 ICl(g) Kp = 81.9 at 25°C
Calculate ΔGrxn for the reaction at 25°C under each of the following conditions:
(a) standard conditions
(b) at equilibrium
(c) PICl = 2.48 atm; PI2 = 0.321 atm; PCl2 = 0.219 atm
a) dG = -RTlnK
b) dG at equilibrium is zero
c) I suppose c means immediately after those conditions are used and before it re-establishes equilibrium. Substitute the values, solve for Qsp and recalculate dG.
Note: for c remember
dG = dGo + RTlnQ
