Question based on 2nd Law of thermodynamics | Spontaneity of a reaction | Gibbs free energy

Define Gibb’s free energy.

What is Gibb’s free energy?

Define Gibb's free energy .

Explain spontaneity of a process in terms of Gibbs energy.

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) ?

Write three statements for 2nd law of thermodynamics.
