Solution

The correct option is B +ve, -ve
$2 O_{3} (g) \to 3 O_{2} (g); △ H = - v e (g i v e n); n o w, △ S = + v e$
as the moles of gas are increasing.

We also know,
and $△ G$ = $△ H$ - $T △ S$
from the given values
$△ G$ = $- v e$ - $(+ v e)$
= $- v e$
So, $△ G$ will be negative for this.

For the reaction 2O3(g)→3O2(g),△H is negative, △S and △G are respectively:

The correct option is B +ve, -ve2O3(g)→3O2(g);△H=−ve(given);now,△S=+ve as the moles of gas are increasing. We also know, and △G= △H - T△S from the given values △G =−ve - (+ve) =−ve So, △G will be negative for this.
