(a) Calculate AH for the producti this reaction. (b) Calculate AH for the production of 9.00 g of AgCl. (c) Calculate AH when 9.25 × 10¯4 mol of AgCl dis- solves in water. 46 At one time, a common means of forming small quantities of oxygen gas in the laboratory was to heat KCIO3: 2 KCIO3(s) –→ 2 KC1(s) + 3 O2(8) AH = -89.4 kJ For this reaction, calculate AH for the formation of (a) 1.36 mol of O2 and (b) 10.4 g of KCl. (c) The decomposition of KC1O3 proceeds spontaneously when it is heated. Do you think that the reverse reaction, the formation of KC1O3 from KCl and O2, is likely to be feasible under ordinary conditions? Explain your answer. 7 Consider the combustion of liquid methanol, CH3OH(1): CH3OH(1) + ¿O2(g) → CO2(g) + 2 H2O(1) AH = -726.5 kJ %3D (a) What is the enthalpy change for the reverse reaction? (b) Balance the forward reaction with whole-number co- efficients. What is AH for the reaction represented by thi: equation? (c) Which is more likely to be thermodynami cally favored, the forward reaction or the reverse reaction (d) If the reaction were written to produce H,O(g) instea of H20(1), would you expect the magnitude of AH to ir crease, decrease, or stay the same? Explain. 8 Consider the decomposition of liquid benzene, C,H6(1), gaseous acetylene, C2H2(8): C,H6(1) → 3 C2H2(g) AH = +630 kJ %3D
