Answer:
We know \[H=U+PV\]
\[({{H}_{2}}-{{H}_{1}})=({{U}_{2}}-{{U}_{1}})+P({{V}_{2}}-{{V}_{1}})\]
\[\Delta
H=\Delta U+P\Delta V\]
For ideal gas \[PV=nRT\,\,\,\,\,\,\,\,\,\,\,......(i)\]
\[\therefore \]\[P\Delta
V=\Delta {{n}_{g}}RT\]
From (i) and (ii)
\[\Delta
H=\Delta U+\Delta {{n}_{g}}RT\]
Where \[\Delta
{{n}_{g}}=({{n}_{2}}-{{n}_{1}})\]
= Number of gaseous moles of
products
- Number of gaseous moles of
reactants
