  1. The decomposition of potassium chlorate (KClO₃) can be represented by the following balanced chemical equation: kClO₃(s) → KCl(s) + O₂(g) The rate law for this reaction is determined experimentally to be: Rate = k[KClO₃] What does this rate law indicate about the effect of KClO₃ concentration on the speed of the reaction? a) Increasing KClO₃ concentration increases the reaction rate. b) Decreasing KClO₃ concentration decreases the reaction rate. c) The reaction rate is independent of KClO₃ concentration. d) The reaction rate increases proportionally to the square of the KClO₃ concentration.
