Um sistema que contm Acetona, 35mol%, e Metanol est confinado em um recipiente fechado e em equilibrio com a fase vapor e mantido a 20 bar e 30C. Para a avaliao do comportamento desta mistura, pode-se admitir que as duas fases esto em equilibrio entre si. Determine as frates dos respectivos componentes na fase vapor, considerando vlidas as seguintes suposies:
a) As fases, liquida (NRTL) e vapor (Equao Generalizada de Virial truncada no 3 termo) no so ideais;
b) A fase vapor ideal e a fase lquida (Equao Generalizada de Virial truncada no 3 termo) no ideal;
c) Utilize as consideraes do ponto a) e determine a variao da energia interna, entalpia, energia livre de Gibbs, energia livre de Helmondtz;
d) Explore o efeito da presso, na fase vapor, sobre o factor de compressibilidade, na faixa de presso entre 1 e 500 bar;
e) Determine o factor de compressibilidade e o volume da mistura para a fase vapor e faa anlise dos resultados obtidos.
