Consider the process
which is carried out at constant pressure. The total DS for this process is known to be 75.0 J K-1mol-1. For A(l) and A(g), the Cp values are 75.0 JK-1mol-1 and 29.0 JK-1mol-1, respectively, and are not dependent on temperature. Calculate ΔH vaporization for A(l) at 125oC (its boiling point).
Answer to relevant QuestionsA sample of ice weighing 18.02 g, initially at 230.0oC, is heated to 140.0oC at a constant pressure of 1.00 atm. Calculate q, w, ΔE, ΔH, and ΔS for this process. The molar heat capacities (Cp) for solid, liquid, and ...What determines ΔSsurr for a process? To calculate ΔSsurr at constant pressure and temperature, we use the following equation: ΔSsurr = 2ΔH/ T. Why does a minus sign appear in the equation, and why is ΔSsurr inversely ...Using Appendix 4 and the following data, determine So for Fe(CO)5(g). Fe(s) + 5CO(g) → Fe(CO)5(g) ΔSo = ? Fe(CO)5(l) → Fe(CO)5(g) ΔSo = 107 J/ K Fe(s) + 5CO(g) → Fe(CO)5(l) ΔSo = –677 J/ K From data in Appendix 4, calculate ΔHo, ΔSo, and ΔGo for each of the following reactions at 25oC. a. CH4(g) + 2O2(g) → CO2(g) + 2H2O(g) b. 6CO2(g) + 6H2O(l) → C6H12O6(s) + 6O2(g) Glucose c. P4O10(s) + 6H2O(l) ...For the reaction 2O(g) → O2(g) a. Predict the signs of ΔH and ΔS. b. Would the reaction be more spontaneous at high or low temperatures?
