G for non-equilibrium

Postby JennyCKim1J » Tue Feb 06, 2018 9:59 am

For the equation deltaG=G+R*T*lnQ, what is Q?

Q is the reaction quotient. You use the same formula to calculate K (equilibrium constant) to calculate Q in a non-equilibrium state.

K would be the equilibrium constant and Q is the constant used to understand the ratio between product and reactants at a certain time, therefore, when you use this equation the Gibbs free energy at standard state, can be equal to -RTlnK so you can all of these together and find the Gibbs Free Energy at Standard State.
