Heat of reaction is defined as the amount of heat absorbed or evolved at a given temperaturewhen the reactants have combined to form the products is represented by a balanced chemcial equation. If the heat is denofed by q then the numerical value of q depends on the manner in which the reaction is performed for the two methods of conducting chemical reactions in calorimeters.
Constant volume W = 0 and `q_(v) = Delta E` Bomb calorimeter
Constant pressure W = - V `Delta`P, therefore `q_(P) = Delta E + P Delta V rar (V. Delta P)`
The heat capacity of a bomb calorimeter is 300 JK When 0.16 gm of methane was burnt in this calorimeter the temperature rose by `3^(@)`C. The value of `Delta`U per mole will be

The total amount of heat evolved or absorbed in a reaction depends upon the number of steps in which the reaction takes place.

The heat absorbed in a reaction at constant temperature and constant volume is

Chemical reactions are invariably associated with the transfter of energy either in the form of heat or light. In the laboratory, heat changes in physical and chemical processes are measured with an instrument called calorimeter. Heat change in the process is calculated as {:(q = ms DeltaT,,s ="Specific heat"),(=cDeltaT,,c ="Heat capacity"):} Heat of reaction at constant volume is measured using bomb calorimeter. q_(V) = DeltaU = Internal energy change Heat of reaction at constant pressure is measured using simple or water calorimeter. q_(p) = DeltaH q_(p) = q_(V) +P DeltaV DeltaH = DeltaU +DeltanRT The heat capacity of a bomb calorimeter is 500 JK^(-1) . When 0.1g of methane was burnt in this calorimeter, the temperature rose by 2^(@)C . The value of DeltaU per mole will be
