In this study of the reaction between the iodide ion and persulfate ion: S20;2 + 21 → I2 + 2SO,² we have chosen to express the rate as the change in the concentration of persulfate ion, S2Og², per unit time. Since persulfate ion is being consumed in the reaction, the concentration is decreasing and the rate of change is negative. As an equation we can write: Rate = -AS2O§² /At If we were to instead express the rate as the change in concentration of iodine, I2. per unit time, which of the following statements would be true (Select all that apply) the concentration of iodine is increasing the rate would be positive the rate would be negative O the rate could be expressed as Al2/At the concentration of iodine is decreasing none of these statements are correct, the rate cannot be expressed this way O O O O O O

Question
In this study of the reaction between the iodide ion and persulfate ion: S2032 + 21 → 2 + 2SO42 we have chosen to express the rate as the change in the concentration of persulfate ion, S2Og2, per unit time. Since persulfate ion is being consumed in the reaction, the concentration is decreasing and the rate of change is negative. As an equation we can write: Rate = -AS2O§² / t If we were to instead express the rate as the change in concentration of iodine, l2. per unit time, which of the following statements would be true? (Select all that apply) the concentration of iodine is increasing the rate would be positive the rate would be negative the rate could be expressed as A2/At the concentration of iodine is decreasing none of these statements are correct, the rate cannot be expressed this way
