Entropy

Animals opera...

Question

Animals operate under conditions of constant pressure and mot of the processes that maintain life are electrical (in a broad sense). How much energy is available for sustaining this type of muscular and nervous from activity from the combustion of 1 mol of glucose molecule under standard conditions at $37$ (blood temperature)? The entropy change is $+ 210 {J K}^{- 1}$ for the reaction as stated.
${Δ H}_{c o m b u s t i o n (g l u c o s e)} = - 2808 k J$

Solution

Here available energy $= △ G$
$△ G = △ H - 7 △ S$
$= - 2873.1 K J$
