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 piston/cylinder setup contains 1 kg of air at 20°C with an initial volume of V1=0.1 m3, as shown in Fig. Q7. Initially, the piston rests on some stops, but it is possible for it to move within the cylinder without friction. To lift the piston and start such motion, an air pressure of 1400 kPa is required. Now, heat is transferred to the system so that the temperature of the air reaches to a final value of 300°C. Fig. Q7 A. Which statement is true? The air can lift the piston before the temperature reaches to 300°C The air cannot lift the piston before the temperature reaches to 300°C

A hot benzene vapor stream at 500oC and 1 bar is rapidly cooled by mixing with liquid benzene at 25oC and 1 bar. The stream leaving the mixer must be 200oC and 1 bar. Assume the reactor is at constant volume. Determine the flow rate (in mol/hr) of the liquid benzene feed stream assuming the flow rate of the hot benzene vapor stream is fixed at a certain value x (specified in the quiz question). Use the polynomial approximations for heat capacity and Table B.20 when appropriate. Assume the flow rate of the hot benzene vapor stream is fixed at 1,253 mol/hr and the liquid benzene feed stream is your reference state. What flow rate (mol/hr) of the liquid benzene feed stream must be used? Round your answer to the nearest tenth and do not include units. Use Tables B.17 and B.20 to tabulate relevant data. Remember that temperatures for polynomial heat capacities are in Kelvin.
