In the manufacture of `NH_(3)` by Haber process `N_(2)(g) + 3H_(2)(g) to 2NH_(3)(g)` the rate of the reaction was measured as -`(d[N_(2)])/(dt) = 2 xx 10^(-4) "mol" L^(-1)s^(-1)`. The rate of the reaction expressed in terms of `H_2` is:

A

`6.6 xx 10^(-5)`

B

`6 xx 10^(-4)`

C

`2 xx 10^(-4)`

D

`4 xx 10^(-4)`
