Mixing of `N_(2)` and `H_(2)` from an ideal gas mixture at room temperture in a container for this process which of the following statement is true

Options

A. `triangle_(H)=0,triangleS_("surrounding") =0 triangle s_("system")=0` and `triangleG=-ve`
B. `triangle_(H)=0,triangleS_("surrounding") =0 triangles_("system") gt 0` and `triangleG=-ve`
C. `triangle_(H)gt 0,triangleS_("surrounding") =0 triangles_("system") gt 0` and `triangleG=-ve`
D. `triangle_(H)lt 0,triangleS_("surrounding") gt 0 triangles_("system") lt 0` and `triangleG=-ve`

Answer

D

Explanation

(i) `because N_(2)(g)+3H_(2)(g) rarr 2NH_(3)(g)`
Favourable conditional low temperature and `trianglen=2 -4=(-) 2 i.e (-) ve` also
(ii) `because triangleS_("univ")=triangleS_("surrounding")+triangle S_("system")` and `triangle G` to be (-) ve i.e (spntaneous) at room temperature
`triangleS_("system")lt0`and `triangleS_("univ")gt0`
