Free energy

Postby Lara Kristine Bacasen 1L » Sun Feb 16, 2020 3:07 pm

Can someone explain why the reaction free energy depend on pressure and the equilibrium constant?

The pressure of a system and the ratio of products to reactants affects how much energy can be produced.

If the reaction is at equilibrium, Q=K and ΔG=-RTlnK. If you increase the partial pressure of a product gas, ΔG becomes more positive. If you increase the partial pressure of a reactant gas, ΔG becomes more negative. Therefore, ΔG depends on pressure and K.
