What is the free energy criterion for a process to occur spontaneously?

For a process to be spontaneous :

For a reaction to occur spontaneously

For a reaction to occur spontaneously

Assertion (A): The thermodynamic factor which determines the spontaneity of a process is the free energy. For a process to be spontaneous the free energy must be-ve. Reason (R ) : The change in free energy is related to the change in a process must always be positive if its is spontaneous.

What is Gibbs free energy ? Derive the relation, Delta_G = DeltaH - T Delta S . Discuss the free energy criterion for the spontaneity of a process.

Any redox reaction would occur spontaneously, if:-

Which of the following reaction does not occur spontaneously?

DeltaH and DeltaS are positive for a chemical reaction. Under what conditions is the reaction expected to occur spontaneously?

Free energy change for a reversible process is

Which of the natural process is spontaneous
