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.
A 15.6 mL sample of vinegar, containing acetic acid, HC2H3O2, was titrated using 0.6216 M NaOH solution. The titration required 19.80 mL of the base. Assuming the density of the vinegar to be 1.0 g/mL, what was the percent (by mass) of acetic acid..
