e. 2N H 4 N O 3 ( s )?2 N 2 ( g ) + O 2 ( g ) + 4 H 2 O( g )

Answer 1

Answer #1

Answer is option e. 2N H 4 N O 3 ( s )?2 N 2 ( g ) + O 2 ( g ) + 4 H 2 O( g ).

In the above reaction two mole of the solid poduce the nitrogrn gas and oxygen gas and water gas.

Entropy is increases by change of the state of molecule to follows the following order.

Solid < Liquid < gases.

The gas molecule is high entropy than the all the other state of the matter.
