WebEnergy level diagrams. are used to model energy. changes during reactions. They show the relative energy levels of the products and reactants . Exothermic reaction WebQ C = 400 J. Q H = W + QC. QH = 300 J + 400 J. Q H = 700 J. Heat delivered to the higher temperature reservoir is 700 J. 2. A reversible heat engine receives 4000 KJ of heat from a constant temperature source at 600 K. If the surrounding is at 300K then determine (a) the availability of heat energy (b) unavailable heat.
