The value of `K_(p)` at `298 K` for the reaction
`1/2 N_(2)+ 3/2 H_(2) hArr 2NH_(3)`
is found to be `826.0`, partial pressure being measured atmospheric units. Calculate `DeltaG^(ɵ)` at `298 K`.

Text Solution

Verified by Experts

`triangleG^(0)=-2.303 RT log K_(p)`
`=-2.303 xx 1.98 xx 298 xx log 826`
=-3980 calories.
