Which of the following expression is correct

Options

  1. AΔG = - RTlnK
  2. BΔG = 1 RT 2 lnK
  3. CΔG 0 = - RTlnK
  4. DΔG 0 = - 1 RT 2 lnK

Correct answer

C. ΔG 0 = - RTlnK

Step-by-step solution

Gibbs free energy is related to standard Gibbs free energy according to the equation. ΔG = ΔG ° + RTlnQ Where Q is Reaction quotient. As we know at equilibrium Change in Gibbs free energy will be zero. And value of Q will be equal to the value of equilibrium constant. Putting these values in equation undefined ΔG o = - RTlnK
