Hydrolysis of sucrose gives, Sucrose + H_2O hArr Glucose + Fructose

1.	Hydrolysis of sucrose gives, Sucrose + H_2O hArr Glucose + Fructose Equilibrium constant K_c for the reaction is 2xx10^13 at 300 K. Calculate DeltaG^ө at 300 K.
Answer» Solution :`DeltaG^ө`=-RT LN `K_c` =-2.330 RT `log_10 K_c` `therefore DeltaG^ө =-2.303 (8.314 "J mol"^(-1)K^(-1)) (300 K) log (2xx10^13)` =-2.303(8.314)(300)(13.3010) =-76336.4 `=-7.634 XX 10^4 "J mol"^(-1)`
