Calculate the equilibrium constant (k) at 298 K and 600 K given that delta G not = 454.59 kJ.

Answer 1

The relationship between K and ΔG°:

lnK = -ΔG/RT or K = e^-ΔG/RT

There are things to watch for: ΔG in J/mol, R = 8.314 J/mol K, and T in Kelvin

K = e^{-454,590J/(8.314*200)} = 1.8 x 10^-119 Pretty unlikely!

I'll leave 600K for you.
