At constant pressure (∆P=0)

Than, Enthalpy

∆H=∆U+∆(PV)

∆H=∆U+P∆V+V∆P; But as (∆P=0)

∆H=∆U+P∆V

But if the Volume is constant (∆V=0)

Than the equation becomes

∆H=∆U+V∆P

What does this Equation implies and what is it's application?

C_{3} H_{8 (g)} + 5 O_{2 (g)} ⇌ 3 C O_{2 (g)} + 4 H_{2} O_{(l i q)}

Δ H - Δ E
