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 For which reaction will DeltaH = DeltaU ? Assume each reaction is carried out in an open container.

For the reaction, N_(2(g)) + 3H_(2(g)) rarr 2NH_(3(g)) . Heat of reaction at constant volume exceeds the heat of reaction at constant pressure by the value of xRT. The value of x is______

For a reaction 2A(g)+2B(g) rarr 2C(g)+D(g) . If heat of reaction at constant pressure is -28 K.cal. The heat of reaction at constant volume at 27^(@)C is

Which of the following reactions have same heat of reaction at constant pressure and at constant volume?
