Consider the reaction with the rate law, Rate = k[BrO3-][Br-][H+]2 By what factor does the rate change if the concentration of BrO3- is tripled and that of Br- is tripled? Just put in the number as a whole number or fraction.
Use Le Chatelier's Principle and the weak acid dissociation equilibrium to explain how the addition of NaOH will completely neutralize an unknown weak acid at the equivalence point in a titration. Consider that hydroxide ion reacts directly with H..
