In ΔG = ΔH - TΔS, what does TΔS represent?
AHeat of the reaction
BTotal energy of system
CEnergy not usable as work
DPressure-volume work done
Answer & Solution
Correct answer: C. Energy not usable as work
TΔS is the part of the energy that cannot be used for useful work, leaving ΔG as the useful part.
