QuestionThermodynamics / coupled reactions (Hess's law)
Consider the following reaction :
Glucose – 6 – Phosphate + Creatine → Glucose + Creatine – P (Creatine phosphate)
What is the value of ΔG° for the reaction given above ?
[Given : The ΔG° values for the hydrolysis of Creatine – P and Glucose – 6 – Phosphate are :
Creatine – P + H₂O → Creatine + P, ΔG° = – 30.0 kJ mol⁻¹
Glucose – 6 – Phosphate + H₂O → Glucose + P, ΔG° = – 11.8 kJ mol⁻¹ ]
- (a) –10.2 kJ mol⁻¹
- (b) 12.2 kJ mol⁻¹
- (c) 18.2 kJ mol⁻¹
- (d) 24.8 kJ mol⁻¹
