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.

Options

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