Spontaneity of a process

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.

Statement: The thermodynamics functions which determines the spontaneity of a process is the free energy. For a process to be spontaneous, the change in free energy must be negative. Explanation:The change in free energy is related to the change in enthalpy and change in entropy. the change in entropy for a process must be always positive if it is spontaneous.

I. Read the following passage and answer questions 1-5 that follows: Spontaneity means the feasibility of a reaction.Gibbs free energy (G) is the thermodynamic quantity which helps in predicting the spontaneity of a process G = H - TS The change in free energy is represented by Gibbs Helmoltz equation, DeltaH - DeltaH - TDeltaS For spontaneity of a process, DeltaG must be negative.It depends upon energy factor (DeltaH) and entropy factor (TDeltaS) . 1. What are the signs of DeltaH and DeltaS for the reactions : 2CI(g) to CI_(2)(g) ?

Considering entropy (S) as a thermodynamics parameter, the criterion for the spontaneity of any process is

Considering entropy (S) as a theromodynamic parameter, the criterion for the spontaneity of any process is

How does T DeltaS determine the spontaneity of process?
