In this video you will be introduced to standard state conditions and learn to calculate gibbs free energy for non-standard conditions from the gibbs free energy for standard conditions. This is done by considering the temperature and reaction quotient for a reaction at non-standard conditions. You will also learn how to determine an equilibrium constant from the gibbs free energy at standard conditions. For an introduction to gibbs free energy see this video: • How to determine the sign of Gibbs Free En... The problem worked in this video is from the openstax chemistry textbook chapter 16, problem 61.
