When 120 mg of naphthalene, C10H8(s), was burned in a bomb calorimeter the temperature rose by 3.05 K
E2C.4(a) When 120 mg of naphthalene, C10H8(s), was burned in a bomb calorimeter the temperature rose by 3.05 K. Calculate the calorimeter constant. By how much will the temperature rise when 150 mg of phenol, C6H5OH(s), is burned in the calorimeter under the same conditions?
E2C.8(a) Estimate ΔrHΘ (500 K) for the reaction C(graphite) + O2(g) → CO2(g) from the listed value of the standard enthalpy of formation of CO2(g) at 298 K in conjunction with the data on the temperature-dependence of heat capacities given in Table 28.1.
E2E.4(a) A sample of carbon dioxide of mass 2.45 g at 27.0°C is allowed to expand reversibly and adiabatically from 500 cm3 to 3.00 dm3. What is the work done by the gas?
