Which of the following devices is best suited to measure the enthalpy changes that accompany combustion reactions?

Question

Quizplus · Accepted Answer

The bomb calorimeter is best suited to measure the enthalpy changes that accompany combustion reactions because it operates at constant volume, allowing for the enthalpy change to be solely attributed to the combustion reaction and not any work or pressure changes. The sample is burned in a high-pressure oxygen environment and the resulting heat is absorbed by the surrounding water, which allows for the calculation of the enthalpy change.
