A kinetic study is reported of the exchange reactions of substituted phenoxide ions with some ring‐substituted 2,4,6‐trinitrophenyl ethers in water. The βrønsted diagrams formed by plotting log k, where k is the second‐order rate constant for reaction, versus pKa show a distinct change in slope when ΔpKa = 0 (ΔpKa being the difference in pKa values of the leaving group and nucleophile). This is consistent
