Chemistry Assignment Help with Pressure Volume Work

7.6 Pressure-Volume Work

7.6.1 Work Done in Reversible Isothermal Expansion



dw = – (Pext – dp). dV

= – Pext. dV = – PdV



w =

w = – nRT ln

w = – 2.303 nRT log

Since temp is constant therefore P1V1=P2V2

wrev = – 2.303 nRT log

7.6.2 Irreversible Isothermal Process

w = – Pext(V2 – V1)

Pext is less than the pressure of the gas, the work done during intermediate expansion is numerically less than during reversible isothermal expansion.

7.6.3 Reversible Adiabatic Process

Work done =
