Animals operate under conditions of constant pressure and most of the processes that maintain life are isothermal (in a broad sense). How much energy is available for sustaining this type of muscular and nervous activity from the combustion of 1 mol of glucose molecules under standard conditions at `37^(@)` C (blood temperature) ? The entropy change is + 182.4 `JK^(-1)` for the reaction stated above
`DeltaH_("combustion")["glucose"] = -2808` kJ

Options

A. `-2754.4 KJ`
B. `2864.5 KJ`
C. `-56.5 KJ`
D. `-2808 KJ`

Answer

B

Explanation

`DeltaG=DeltaH-TDeltaS`
`=-2808-310xx182.4xx10^(-3)=-2864.5 KJ`
