Which one of the following equation is correct forr the reaction : `N_(2)(g)+3H_(2)(g)rarr2NH_(3)(g)` ?

Options

A. `(3d[H_(2)])/(dt)=(2d[N_(2)])/(dt)`
B. `(2d[N_(2)])/(dt)=(1)/(3)(d[H_(2)])/(dt)`
C. `(2d[NH_(3)])/(dt)=(-3[H_(2)])/(dt)`
D. `(3d[NH_(3)])/(dt)=(-2d[H_(2)])/(dt)`

Answer

D

Explanation

`N_(2)(g)+3H_(2)(g)rarr 2NH_(3)(g)`
`-(d[N_(2)])/(dt)=(-1)/(3)(d[H_(2)])/(dt)=(1)/(2)(d[NH_(3)])/(dt)`
`:. 3(d[NH_(3)])/(dt)=(-2d[H_(2)])/(dt)`.
