Hydrolysis of sucrose gives
`"Sucrose" +H_(2)OhArr"Glucose + Fructose"`

Equilibrium constant `K_(c)` for the reaction is `2xx10^(13)` at `300 K`. Calculate `DeltaG^(ɵ)` at `300 K`.

Text Solution

Verified by Experts

`DeltaG^@`=`-2.303 RT log K`
`K=2xx10^13 , T=300 K, R= 8.314 "J mol"^(-1) K^(-1)`
`therefore DeltaG^@=-2.303xx(8.314 "J mol"^(-1)K^(-1))xx(300K)xxlog 2 xx10^13`
`=-7.64xx10^4 "J mol"^(-1)`
`=-76.4 "kJ mol"^(-1)`
