THERMOCHEMISTRY 237 23 3. A student wishes to determine the enthalpy of the reaction of hydrogen gas with chlorine gas by the reaction represented below. A high-pressure bomb calorimeter is used for this experiment. A 500.-mL high-pressure cell is filled with an equimolar mixture of H,(g) and CL,(g) to a total pressure of 10.00 atm and 293.50 K. H,(g) + CL(g) → 2 HCI(g) (a) If the reaction goes to completion, how many moles of HClI(g) can be produced? (b) The high-pressure sealed cell was placed in the bomb calorimeter and the mixture was ignited with an internal spark. The temperature of the calorimeter rose from 293.50 K to 298.83 K. If the previously-measured heat capacity of the whole calorimeter was C 3.60 kJ/K, calculate the heat transferred to the calorimeter by the reaction.
