Benzoic acid, C;HsO:H, is typically used as a çalibrant for determining the specific heat of bomb calorimeters. It combusts via the following unbalanced chemical reaction: C,H5O2H (s) + 02(g) → CO2 (g) + H2O(1) 3. For this experimental setup and reaction, the constant volume heat flow is known to be gy = -26.979 kJ. Over the course of the reaction, the temperature rose from 19.863 °C to 22.540 °C. Calculate the heat capacity, Cou, for this calorimeter in kJ °C-!.

(a) Suppose that attractions are the dominant interaction between gas molecules, and the equation of state is p = nRT/V – n2a/V2. Determine the work (W(non-ideal gas)) of reversible, isothermal expansion of such a gas from initial volume V (initial) = 20.0 L to final volume V(final) = 40.0 L if n = 2.00 mol, T = 300 K, and a = 3.621 atm-L2/mol2. Watch your units. (b)Determine the work (W(ideal gas) of reversible, isothermal expansion of an ideal gas from initial volume V (initial) = 20.0 L to final volume V(final) = 40.0 L if n = 2.00 mol and T = 300 K. (c) Show the difference W(non-ideal) – W(ideal). If all your calculations are done correctly, this result shows you the effect of attractive interaction between gas particles on the work done by the system.

Q2: One mole of an ideal gas, initially at 40°C and 1 bar, is changed to 140°C and 12 bar by three different mechanically reversible processes: a- The gas is first heated at constant volume until its temperature is 140°C; then it is compressed isothermally until its pressure is 12 bar. b- The gas is first heated at constant pressure until its temperature is 140°C; then it is compressed isothermally to 12 bar. c- The gas is first compressed isothermally to 12 bar; then it is heated at constant pressure to 140°C. Calculate Q, W, AU, and AH in each case. Take CP = (7/2)R and CV (5/2)R. Alternatively, take CP = (5/2)R and CV (3/2)R.
