A reaction attains equilibrium, when the free energy change is

At equilibrium the free energy change (Delta G) is :

What is the value of free energy chnage for a reaction in equilibrium state? (b) How is free energy change related to equilibrium constant of the reaction?

If equilibrium constant for a reaction is K, then standard free energy change is :

If equilibrium constant for a reaction is 'K', then standard free energy change is :

State the condition of spontaneity and equilibrium in terms of Gibbs free energy change of a system.

For the equilibrium reaction, the value of Gibbs free energy change is:

Write the relationship between standard free energy change and the equilibrium constant of a reaction. What is the sign of standard free energy change when the equilibrium constant is less than one?
