Question

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

Answer 1

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