Prob. 13.69

For one of the following substances, determine P^sat∕bar from the Redlich/Kwong equation at two temperatures: T = T_n (the normal boiling point), and T = 0.85T_c. For the second temperature, compare your result with a value from the literature (e.g.,Perry’s Chemical Engineers’ Handbook). Discuss your results.
