Free energy of reaction

Postby Seohyun Park 1L » Wed Feb 20, 2019 6:54 pm

Why does the free energy of a reaction (not the standard free energy) depend on the pressure and equilibrium constant?

The free energy equation is deltaG = deltaG(standard) + RTlnK.
K is the equilibrium constant, so the free energy depends on the equilibrium constant. Sometimes, when given partial pressures, they are used to calculate the equilibrium constant.
