Monolayer and specific surface area values have been reported for fourteen different organic vapours adsorbed on charcoal. Five well known equations namely Langmuir. Joyner, Kaganer, Reciprocal pressure - volume and BET were employed using IBM 360 - G44 computer programme for computations. Comparison of Joyner and BETA monolayer values is given for four organic compounds whilst monolayer and specific surface area values are reported and discussed for fourteen organic compounds adsorbed on charcoal.
