Following reaction occurs at `25^(@)` :
`2NO(g, 1xx10^(-5)atm) + CI_(2)(g, 1 xx 10^(-2)atm)hArr 2NOCI(g,1 xx 10^(-2)atm)`
Calculate `DeltaG^(@) [R = 8 J//"mole" K]`

Text Solution

Verified by Experts

The correct Answer is:
`-43.92 KJ`
`2NO (9,1xx 10^(-5) atm) + CI_(2)(9, 1 xx 10^(-2)) hArr 2NOCI(9, 1 xx 10^(-2))`
`DeltaG^(@) =- 2.363 "RT" ("log" ((1 xx 10^(-2))^(2))/((1 xx 10^(-5))^(2) (1 xx 10^(-2)))) =- 2.303 "RT"["log" (1 xx 10^(2))/(1 xx10^(-10))]`
`=-2.303 "RT"["log" 1 xx 10^(8)] =- 2.303 xx 8 xx 298 xx 8 =- 43.92` KJ.
