How much energy (in kJ) is available for muscular and nervous activity from the oxidation of 1.0 mole of a sugar under standard conditions at 27°C? The standard entropy and enthalpy of reaction are +1

Question

How much energy (in kJ) is available for muscular and nervous activity from the oxidation of 1.0 mole of a sugar under standard conditions at 27°C? The standard entropy and enthalpy of reaction are +180 J/K-mol and -2600 kJ/mol, respectively.

Answer:

2654.00

Solution:

Δ G^° = Δ H - TΔ S = -2600 - 300×0.180 = -2600 - 54 = -2654 kJ. Available energy = 2654 kJ. Ans = 2654.
