Do you expect `DeltaS` to be `+ve, -ve`, or zero for the reaction
`H_(2)(g) +I_(2)(g) hArr 2HI(g)`

Explanation

To determine the change in entropy (ΔS) for the reaction:

\[ H_2(g) + I_2(g) \rightleftharpoons 2HI(g) \]

we can follow these steps:

### Step 1: Understand the concept of entropy (ΔS)
Entropy (ΔS) is a measure of the disorder or randomness of a system. A positive ΔS indicates an increase in disorder, while a negative ΔS indicates a decrease in disorder. If there is no change in the number of moles of gas, ΔS is expected to be zero.
