The equilibrium reaction that is not influenced by volume change at constant temperature is :

Options

A. `H_(2(g))+I_(2(g))hArr2HI`
B. `N_(2(g))+3H_(2(g))hArr2NH_(3(g))`
C. `N_(2)O_(4(g))hArr2NO_(2(g))`
D. `2NO_((g))+O_2hArr2NO_(2(g))`

Answer

A

Explanation

`H_(2(g)) +I_(2(g)) hArr 2HI_((g))`
`Deltan_(g) =2 -(1+1) =0`
As the total number of molecules of the reactants are equal to the number of molecules of product, hence this reaction is not influenced by volume change.
