Choose the corrent pair.

Answer»

`H_(2(G)) + I_(2(g)) hArr 2HI_((g)) : Delta n_(g) = -ve`
`PCl_(5(g)) hArr PCl_(3(g))+ Cl_(2(g)) : Delta n_(g) = -ve`
`N_(2(g)) + O_(2(g)) hArr 2NO_((g)) : Delta n_(g) = + ve`
`2NH_(3(g)) hArr N_(2(g)) + 3 H_(2(g)) : Delta n_(g) = +ve`

Solution :`Delta n_g = 2-2 =0, (b) Delta n_(g) = 2-1=1 : (C) Delta n_(g) =2-2= 0`
