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)` ?

Explanation

To determine the signs of ΔH (enthalpy change) and ΔS (entropy change) for the reaction:

\[ 2 \text{Cl(g)} \rightarrow \text{Cl}_2\text{(g)} \]

we will analyze the reaction step by step.

### Step 1: Analyze the Reaction
The reaction involves two moles of chlorine gas (Cl) combining to form one mole of chlorine gas (Cl2).
