Question

Eric has just had a sandwich that contained the equivalent of 1.80 mol of glucose the standard molar entropy of reaction is 182 j k-1 mol-1. how much energy (in kj) is available for sustaining eric's muscular and nervous activity assuming a body temperature of 36.9oc

Answer 1

Energy available for sustaining Eric's muscular and nervous activity can be calculated by,

Energy available= Standard molar entropy×Number of moles×Temperature

We have, standard molar entropy of glucose = 182 J/K mol

Number of moles of glucose = 1.80 mol

Body temperature = 36.9° C = 36.9 + 273.15 = 310.05 K

Substituting the value we get,

Energy available = 182×1.80×310.05 = 100,456.2 J
