Theory of Bomb Calorimetry.

... Theory of Bomb Calorimetry: The purpose of this experiment is to learn how to apply the laws of thermodynamics to chemical reactions. In this particular experiment we will use a bomb calorimeter to study heats associated with combustion reactions. A bomb calorimeter is a device used for measuring the standard heat of combustion associated with a chemical reaction. The standard heat of combustion for a substance is defined as the enthalpy change, accompanies a process in which one mole of a substance undergoes a combustion reaction with oxygen. It can be found according to equation 1. 1) H- Enthalpy; R - Gas Constant; n - number of moles; U - Internal Energy; s - denotes sample combusted; 0 - denotes standard state (25C, 1bar). The internal energy change of the sample is found from from equation 2, where change in temperature is obtained from experiment and heat capacity of the calorimeter is obtained from standardization
