Problem: Consider the following reaction at 800. K:N2(g) + 3F2(g) → 2NF3(g)An equilibrium mixture contains the following partial pressures: PN2 = 0.021 atm, PF2 = 0.063 atm, PNF3 = 0.48 atm.Calculate ΔG° for the reaction at 800. K.

FREE Expert Solution

Recall that the equilibrium constant is the ratio of the products and reactants

We use Kp when dealing with pressure.


The Kp expression for the reaction is:

Kp=PproductsPreactants=PNF32PN2 PF23


We’re given the following equilibrium pressures:
