The average rate of disappearance of I^- between 400.0 s and 800.0 s is ________ M/s.

Question

Quizplus · Accepted Answer

The average rate of disappearance of I- can be calculated using the formula:Average rate = (Change in concentration) / (Change in time)From the graph, we can see that the change in concentration of I- between 400.0 s and 800.0 s is 5.6 x 10^-5 M. The change in time is 800.0 s - 400.0 s = 400.0 s.Therefore, the average rate of disappearance of I- is:Average rate = (5.6 x 10^-5 M) / (400.0 s) = 1.4 x 10^-5 M/sTherefore, the correct answer is A) 1.4 x 10^-5 M/s.
