व्यंजक `DeltaH = DeltaU + PDeltaV` की व्युत्तपति कीजिए ।

Derive relation DeltaH = DeltaU + Deltan_gRT .

While doing an experiment on bomb calorimeter, a student made the following statement : DeltaH = DeltaU + pDeltaV Since in the experiment DeltaV =0 hence DeltaH = DeltaU .Is the student right or wrong? Justify.

When is DeltaH=Deltau in a reaction?

The relation between DeltaU and DeltaH :

Show that DeltaH=DeltaU+Deltan_((g)),RT

Give an example of a reaction for each of the following relations between DeltaH and DeltaU : (i) DeltaU lt DeltaH (ii) DeltaU gt DeltaH (iii) DeltaU=DeltaH .

In the relation DeltaH = DeltaU + (Deltan_(g))RT the units of Deltan_(g) is mol.

For which change DeltaH ne DeltaU ?
