Chemistry 152 Discussion Section 10.18.11 For several problems the following standard state properties are useful: -1274.45 0 -393.51 -285.84 -276.98 218.16 29.36 37.13 75.30 111.96 1) The respiratory system uses oxygen to degrade glucose to carbon dioxide and water. The net equation is a) Calculate the enthalpy of reaction at 310K. Assume all heat capacities are constant between 298K and 310K. Solution: At T=298K Then Finally: b) Assume respiration occurs at constant pressure. Calculate the amount of heat produced by respiration per mole of oxygen absorbed at 298K. Solution: c) An average person uses about 1.2 moles of oxygen per hour in the course of respiring. Calculate the amount of heat produced by respiration per kilogram per hour by an average person. Assume a weight of 70 kg. Solution: d) Most of the heat produced by the body is lost. But suppose that a person were clothed in a thermally insulated suit such that all the heat from
