For which reaction `DeltaH=DeltaU` ?

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

State the condition at which DeltaH=DeltaU . For which reactions-(i) DeltaHgtDeltaU (ii) DeltaH lt DeltaU ?

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 ?
