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

Text Solution

Verified by Experts

`DeltaS` should be negative because two different molecules `(H_(2)` and `I_(2))` would have more randomnes than two same molecules `(HI)`. Therefore, `DeltaS` decreases.
