How Gibbs free energy is related to enthalpy , entropy and temperature of a system? How itthis used in determining the spontaneity of a process ?

How does T DeltaS determine the spontaneity of process?

Free energy change is related to enthalpy and entropy changes as:

Wha is menat by free energy of a system? How is it related to enthalpy and entropy of the system? How is it useful for predicting the feasibility of a process?

Gibb's Free Energy and Spontaneity

What is free energy? How is it related to the spontaneity of a reaction.

Define free energy and entropy of a system.

Gibb's free energy and spontaneity of a Chemical Reactions

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) ?
