Hydrolysis of sucrose is given by the following reaction. Sucrose + H 2 O ⇌ Glucose + Fructose If the equilibrium constant K C is 2 × 10 13 at 300   K , the value of Δ r G ⊖ at the same temperature will be:
Options
- A8.314   J   mol – 1 K – 1 × 300   K × ln 2 × 10 13
- B8.314   J   mol – 1 K – 1 × 300   K × ln 3 × 10 13
- C– 8.314   J   mol – 1 K – 1 × 300   K × ln 4 × 10 13
- D– 8.314   J   mol – 1 K – 1 × 300   K × ln 2 × 10 13
Correct answer
D. – 8.314   J   mol – 1 K – 1 × 300   K × ln 2 × 10 13
Step-by-step solution
