Conisder the chemical reaction `N_(2)(g) + 3H_(2)(g) rarr 2NH_(3)(g)` The rate of this reaction can be expressed in terms of time derivatives of the concentration of `N_(2)(g), H_(2)(g)`, or `NH_(3)(g)`. Identify the correct relationship among the rate expresisons.A. `"rate "=- d[N_(2)]//dt =-1//3d [H_(2)]//dt =1//2d [NH_(3)]//dt`B. `"rate "=-d[N_(2)]//dt =-3d[H_(2)]//dt =2d[NH_(3)]//dt`C. `"Rate "=d[N_(2)]//dt =-3//3d [H_(2)]//dt = 1//2d[NH_(3)]//dt`D. `"rate "=d[N_(2)]//dt =-d[H_(2)]//dt 1//2s[NH_(3)]//dt`

Answer» Correct Answer - A
From the given equation , we have
`-(d)/(dt)[N_(2)]=-(1)/(3) (d)/(dt) [H_(2)]=(1)/(2) (d)/(dt)[NH_(3)]`
