NTERACTIVE EXAMPLE Reaction Rate Chloromethane reacts with iodide ion to yield iodomethane and chloride ion. CH;C1 +r- CH;I + CF A way to determine the rate of the reaction of chloromethane with iodide ion is to measure the disappearance of T from the solution. Suppose that the concentration of I was 0.21 mol IL at the start of the reaction. At the end of 20 min, the concentration dropped to 0.13 mol L. This difference is equal to a change in concentration of -0.08 mol IL. QUESTION What is the rate of reaction with respect to iodide ion? |× molIL'min
