    It may be added that repeated absorption measurements on the same sample of 2,2′-bipyridine etc. showed that the equilibrium state in chelate formation is generally attained in several hours at most; however, in the case of 2,9-dimethyl-1,10-phenanthroline chelate it was shown that it is necessary to wait overnight to get a truly time-independent absorption curve. This fact shows that there is also a steric effect on reaction velocity.
