Animals operate under conditions of constant pressure and most of the process 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 37ºC (blood temperature) ? The entropy change is + 182. 4 JK –1 for the reaction stated above.
Δ H combustion [glucose] = –2808 KJ
Δ H ngu = –2808 KJ
Text Solution
Verified by ExpertsThe correct answer is:
B
Δ G = Δ H – T Δ S = – 2808 – 310 × 182.4 × 10 –3 = – 2864.5 kJ
