Question

write the mathametical expressions for the relation between heat of reaction at constant pressure and at constant volume ​

Answer 1

Hey mate

Mark it as brainliest

Hope it helps

Solution :

Heat of reaction at constant pressure is enthaply, Qp=ΔH

Heat of reaction at constant volume is internal energy Qv=ΔU

enthapy and internal energy relationship at const pressure as ΔH=ΔU+PΔV

that is Qp=Qv+PΔV

or it can also be written asQp=Qv+nRΔT

constant pressure= constant Volume
