14.9. For one of the substances listed below determine p sat/bar from the Redlich/Kwong equation at two temperatures: T = Tn (the normal boiling point), and T = 0.85Tc. For the second temperature, compare your result with a value from the literature (e.g., Perry's Chemical Engineers' Handbook). Discuss your results.
