In a reaction `N_(2(g))+3H_(2(g))to2NH_(3(g))` rate of appearance of `NH_(3)` is `2.5xx10^(-4)molL^(-1)sec^(-1)` then rate of reaction and rate of disappearance of `H_(2)` respectively is :-

Options

A. `3.75xx10^(-4),1.25xx10^(-4)`
B. `1.25xx10^(-4),2.5xx10^(-4)`
C. `1.25xx10^(-4),3.75xx10^(-4)`
D. `5xx10^(-4),3.75xx10^(-4)`

Answer

C

Explanation

`ROR=(-d[N_(2)])/(dt)=(-d[H_(2)])/(3dt)=(d[NH_(3)])/(2dt)`
`ROR=(d[NH_(3)])/(2dt)`
`ROR=(2.5xx154)/(2)=1.25xx10^(-4)`
`(-d[H_(2)])/(dt)=(3)/(2)(d[NH_(3)])/(dt)=(3)/(2)xx2.5xx10^(-4)=3.75xx10^(-4)`
