Conside the chemical reaction,
`N_(2)(g) + 3H_(2)(g)rarr2NH_(3)(g)`
The rate of reaction can be expressed in terms of time derrivate of concentration of `N_(2)(g), H_(2)(g) or NH_(3) (g)` Identift the correct relationship amongst the rate expression :

Options

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

Answer

A
