ΔG° Relates to K

State

At equilibrium, ΔG equals zero and Q equals K, reducing the nonstandard free energy expression to ΔG° = −RT ln K, linking standard free energy change directly to K.

Show

A large negative ΔG° corresponds to a large K, an equilibrium mixture favoring products heavily.

Watch for

This equation uses K itself, not Q — substituting a nonequilibrium Q gives a meaningless result.
