What is the relationship between standard free energy and free energy

Accepted Answer

Standard free energy and free energy are related through the standard state. Standard free energy is the free energy of a system under standard state conditions, which are typically 298 K and 1 atm. Free energy is the free energy of a system under non-standard state conditions. The difference between standard free energy and free energy is given by the equation ΔG = ΔG° + RTlnQ, where ΔG is the free energy, ΔG° is the standard free energy, R is the gas constant, T is the temperature, and Q is the reaction quotient.
