For the reaction `N_(2)(g)+3H_(2)(g) rarr 2NH_(3)(g)`, under certain conditions of temperature and partial pressure of the reactants, the rate of formation of `NH_(3)` is `0.001 kg h^(-1)`. The same rate of converison of hydrogen under the same condition is................`kg h^(-1)`.

Options

A. `0.0015 "kgh"^(-1)`
B. `1.76xx10^(-4) "kgh"^(-1)`
C. `0.002 "kgh"^(-1)`
D. `0.003 "kgh"^(-1)`

Answer

B

Explanation

`-(1)/(3)(d[H_(2)])/(dt)=(1)/(2)(d[NH_(3)])/(dt)`
`-([dH_(2)])/(dt)=(3)/(2)xx(0.001xx10^(3))/(17) "mol/hr"`
`[-([H_(2)])/(dt)=(0.001xx10^(3))/(17)"mol/hr"]`
`(3)/(2)xx(0.001xx10^(3))/(17)xx2xx10^(-3) "kg/hr"`
`=1.76xx10^(-4)"kg/hr"`
