Consider the chemical reaction, N (2) ...

Consider the chemical reaction,
`N _(2) (g) + 3 H _(2)(g) to 2 NH _(3) (g).`
The rate of this reaction can be expressed in terms of time derivative of concentration of `N _(2) (g), H _(2) (g) or NH _(3) (g).` Identify the correct relationship amongest the rate expression.

A

Rate `=- d [ N _(2) ] //dt = - 1//3d [ H _(2) ] //dt = 1//2 d[NH _(3) ] //dt`

B

Rate `=- d [ N _(2) ] //dt =- 3d [ H _(2) ] //dt = 2d [ NH _(3) ]//dt`

C

Rate `= d [ N _(2) ] /d/t = 1//3d [ H _(2) ] //dt = 1//2d[NH _(3) ] //dt `

D

Rate `= - d [ N _(2) ]//dt =- d [H_(2) ] //dt = d [ NH _(3) ] //dt `
