... out to be zero order in [I2]. This means (see Equation 3) that the rate of the reaction does not depend on [I2] at all; [I2]0 = 1, no matter what the value of [I2] is, as long as it is not itself zero. Because the rate of the reaction does not depend on [I2], we can study the rate by simply making I ...
