The correct answer is B. δG ° = -RT ln K.
The relationship between the equilibrium constant (K) and the standard free energy change (δG °) is given by the equation:
δG ° = -RT ln K
where:
- δG ° is the standard free energy change (in joules per mole, J/mol)
- R is the gas constant (in joules per mole-kelvin, J/mol·K)
- T is the temperature (in kelvin, K)
- ln is the natural logarithm
- K is the equilibrium constant (unitless)
This equation indicates that a negative δG ° (spontaneous process) corresponds to a large K (favors products), while a positive δG ° (non-spontaneous process) corresponds to a small K (favors reactants).
