How much energy (in kJ) is available for sustaining muscular and nervous activity from the combustion of 1.0 mole of glucose molecules under standard conditions at 37°C (body temperature)? The standard entropy and enthalpy of reaction are +200 J/K-mol and -2808 kJ/mol, respectively.

Answer:
2870.00
Solution:

Available (non-expansion) energy is -Δ G° = -(Δ H - TΔ S). TΔ S = 310×0.200 = 62 kJ. Δ G° = -2808 - 62 = -2870 kJ. Available energy = 2870 kJ. Ans = 2870.
