The reaction between benzoyl chloride and aniline in carbon tetrachloride solution is approximately bimolecular, but is anomalous in several respects, especially in showing an unusual fall of the constant with dilution. In hexane the anomalies are accentuated and indicate that the reaction is largely catalysed by the solid particles of the product. The heat of activation is extremely small and variable. Care must be exercised in concluding merely from a small temperature influence that activating collisions are "inefficient, " unless complications such as those found in this example are proved to be absent. Although there are similar catalytic effects in carbon tetrachloride solution, which explain the divergences from a simple bimolecular course, yet they are probably subsidiary to the homogeneous reaction, which itself is much slower than the possible rate of activation, in common with a number of other reactions between neutral molecules in solution.
