A constant pressure adiabatic bomb calorimeter consists of 1) a reaction vessel with diathermal, igid, impermeable walls, 2) a 1.000 kg bath of liquid water that surrounds the reaction vessel, nd 3) adiabatic, rigid, impermeable walls that enclose the liquid water bath. The calorimeter is alibrated by adding 1.00 mol of propane and 5.00 mol oxygen into the reaction vessel and then merforming the combustion reaction: C3H3 (g) + 5 02 (g) → 3 CO, (g) + 4 H20 (1) rior to the reaction, the reactants and water bath are in thermal equilibrium at 298.15K. After he reaction, the products and water bath come to thermal equilibrium at 318.15K. It is assumed hat the reaction goes to completion and that no heat enters the calorimeter from the urroundings. Also assume that the specific heat of each substance is constant over the emperature interval from 298.15K to 318.15K.

Question

Determine the specific heat (at constant pressure) for the reaction vessel and outer walls, i.e., the rest of the calorimeter other than the water bath.

A constant pressure adiabatic bomb calorimeter consists of:

1. A reaction vessel with diathermal, rigid, impermeable walls.
2. A 1.000 kg bath of liquid water that surrounds the reaction vessel.
3. Adiabatic, rigid, impermeable walls that enclose the liquid water bath.

The calorimeter is calibrated by adding 1.00 mol of propane and 5.00 mol of oxygen into the reaction vessel and then performing the combustion reaction:

\[ \text{C}_3\text{H}_8 \, (\text{g}) + 5 \, \text{O}_2 \, (\text{g}) \rightarrow 3 \, \text{CO}_2 \, (\text{g}) + 4 \, \text{H}_2\text{O} \, (\text{l}) \]

Prior to the reaction, the reactants and water bath are in thermal equilibrium at 298.15 K. After the reaction, the products and water bath come to thermal equilibrium at 318.15 K. It is assumed that the reaction goes to completion and that no heat enters the calorimeter from the surroundings. Also assume that the specific heat of each substance is constant over the temperature interval from 298.15 K to 318.15 K.
