1. Equation VI-14a and VI-14b
(∆H│∆E)=-C(S)(T_1-T_0 ) 14a (∆H) and 14b (∆E)
Assume that the heat capacity of the calorimeter is much greater than the heat capacities of the product gases. Assuming C(S)=10.5 kJ/K determine the error in this assumption for the calculated energy of combustion of 1.0 g of benzoic acid using equation VI-12a and VI-12b
∆H= -C_p (C+D+S)( T_1-T_0 ) (12a)
∆E= -C_v (C+D+S)( T_1-T_0 ) (12b)
2. A student carries out the partial molar volume experiment using NaCl dissolved in water. His plot of ϕ vs. √m yield 2.9 as the slope and 16.3 as the y-intercept. Using a spreadsheet plot V1, V2, and V as a function of m for 0 ≤ m ≤ 3 molal. (b) At what value does V1= V2 ? (c) Give a physical interpretation for the behavior of V1, V2 and V as a function of m. (d) What is the change in total volume between 0 and 3 molal?

Physical Chemistry
A Carnot engine operates using a heat source at 500°C, and a heat sink at room temperature (20°C). Suppose that as a heat source, you use the combustion of 100 cubic feet of natural gas at room temperature and pressure (e.g. in a fuel cell of some kind). Under ideal conditions, what is the largest amount of work that can be generated using this Carnot engine? Thank you! (Use the ideal gas law, PV=nRT, with the gas constant R=8.3 J/Kmol)
