Answer B & E
Explanation - increase in entropy means increase in randomness of molecule ( moleucule is more free , more dis arranged .)
Option B - if we increase volume , moleucule will more random to move
Option E - towards product no. Of gaseous molecule is incrased , more random movement of gas Molecule.
In remaining case , increase in pressure & change in solid phase decrease randomness.
