Heat of reaction at constant pressure is………….. .

Heat of a reaction (Q) at constant pressure is equal to

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.

At constant volume and at 298 K , the heat of combustion of sucrose [C_(12)H_(22)O_(11) (s)] is -1348.9 kcal mol^(-1) . If steam is produced during the combuston, the heat of reaction at constant pressure will be

Heat of reaction at constant pressure and volume is 3RT. Find the relation between Kp & Ke for the reaction.

(i) What do you mean by heat of reaction at constannt volume and heat of reaction at constant pressure? (ii) Establish the relation DeltaH=DeltaU=DeltanRT for a chemical reaction in gaseous state.

If Delta E is the heat of reaction for C_(2)H_(5)OH_((1))+3O_(2(g)) rarr 2CO_(2(g))+3H_(2)O_((1)) at constant volume, the Delta H (Heat of reaction at constant pressure) at constant temperature is

If Delta E is the heat of reaction for C_(2)H_(5)OH_((1))+3O_(2(g)) rarr 2CO_(2(g))+3H_(2)O_((1)) at constant volume, the Delta H (Heat of reaction at constant pressure) at constant temperature is
