    Solution to Laboratory Assignment 27

    Analysis of data on vapor pressure of carbon monoxide from Perry's Chemical Engineers Handbook

    Fit to Antoine equation (ln(p) = A - B/(T + C)). Where T is absolute temperature and A, B, CSolution: One linear form is ln(p) = A + (AC-B)/T - C ln(p)/T are constants to be determined.
