For which of the following reactions, `DeltaS gt 0`-

A

`H_(2)(g)+I_(2)(g)hArr 2HI(g)`

B

`HCl(g)+NH_(3)(g) hArr NH_(4)Cl(s)`

C

`NH_(4)NO_(3)(s)hArr to N_(2)O(g)+2H_(2)O(g)`

D

`MgO(s)+H_(2)(g)hArr Mg(s)+H_(2)O(g)`.

Text Solution

Verified by Experts

The correct Answer is:
C
`NH_(4)NO_(3)(s)hArrN_(2)O(g)+2H_(2)O(g)`
With increasing the number of species in the system, the entropy of system increases for which `DeltaS gt0`.
