eaction, it absorbs 824 J of heat from gaS undergoes particulăr its surroundings and has 0.65 kJ of P-V work done on it by its surroundings. What are the values of AH and AE for this a process? P is confined to a cylinder under constant atmospheric pressure, as illustrated in Figure 5.4. When 0.49 kJ of heat is added to the gas, it expands and does 214 J of work on the curroundings. What are the values of AH and AE for this process? 5.39 The complete combustion of ethanol, C2H5OH(I), to form_ H.O(g) and CO2(g) at constant pressure releases 1235 kl of heat per mole of C2H5OH. (a) Write a balanced thermochem- ical equation for this reaction. (b) Draw an enthalpy diagram for the reaction. 540 The decomposition of Ca(OH)2(s) into CaO(s) and H,O(g at constant pressure requires the addition of 109 kJ of hea mole of Ca(OH)2. (a) Write a balanced thermochemica per equation for the reaction. (b) Draw an enthalpy diagram fo the reaction. 41 Ozone, O3(g), is a form of elemental oxygen that plays an im portant role in the absorption of ultraviolet radiation in th stratosphere. It decomposes to O2(8) at room temperatur and pressure according to the following reaction: 2 03(g) → 3 O2(8) AH = -284.6 kJ %3D (a) What is the enthalpy change for this reaction per mo of O3(8)? (k) Which has the higher enthalpy under these conditior 203(g) or 3 0am? (a)?
