The heats of adsorption of carbon tetrachloride, chloroform, methylene chloride, and ethyl chloride were determined by the method of Pearce and McKinley. The effect of temperature on the molecular heats of adsorption is very small. The molecular heats of adsorption, ranging from 12.1 kilogram calories for methylene chloride to 15.4 kilogram calories for carbon tetrachloride, seem to increase with the number of substituted chlorine atoms in the molecule.
