Computer generated monolayer capacity values and surface area values are reported for fourteen different compounds, adsorbed on charcoal. These values are obtained using Langmuir, Joyner, Kaganer and Reciprocal-pressure-volume equations on a IBM 360/G44 Computer programme. Our surface area and monolayer capaicty values differ from the well known BET values; an explana­tion for which is given.
