A) Which of the following statements is true?
I- The disappearance of iodate is three times the
disappearance of sulfite.
II- The disappearance of iodide is the same as the
appearance of iodate.
III- The rate of formation of all the products are the
IV- The rate of disappearance of sulfite is three times
the disappearance of iodate.
