The reaction of 1.40 g of carbon monoxide with excess water vapor to produce carbon dioxide and hydrogen gases in a bomb calorimeter causes the temperature of the calorimeter assembly to rise from 22.113 °C to 22.799 °C. The calorimeter assembly is known to have a total heat capacity (calorimeter constant) of 3.00 kJ · (°C)^–1.

(a) Write a balanced equation for the reaction.

(b) Calculate the internal energy change, ΔU, for the reaction of 1.00 mol CO(g).
