Question
Consider the work for the reversible isothermal expansion of 1 mole of gas. During this expansion, the volume of the gas chances from V1 t V2.
a. First consider the case where V1 is close to the molar volume. Explain how attractive interactions affect the amount of work. Thus, if we could increase the attractive interations in the gas, what would the effect on the work be? And what would be the effect if we decrease the attractive interactions? explain in words, no equatins.
b. Now consider the case where V1 is very, very large. Carefully explain in words how attractive interactions affect the amount of work.
c. Calculate the work for the reversible isothermal expansion of 1 mole of van der Walls gas. Then use your result to explicitly verify your answers to a and b.
van der waals equation is (p+a/v^2)(v-b)=RT
