Nitrite ion reacts with ozone in aqueous solution, producing nitrate ion and oxy

Question

Nitrite ion reacts with ozone in aqueous solution, producing nitrate ion and oxygen: aq) +03(g)- NO (aq) +0,( The following data were collected for this reaction at 298 K Calculate the average reaction rate between 0 and 100 s microseconds and between 200 and 300 Time (us) 0 100 200 300 Oal (M) 1.153-102 9.972 10-3 8.777 103 8.183-103 2nd attempt Part 1 (1 point) lal See Periodic Table Average reaction rate between 0 and 100 s- 1 558 HS Part 2 (1 point) See Hir Average reaction rate between 200 and 300 s-594

Explanation / Answer

average reaction rate= difference in concentration/ change in time

between 0 and 100 seconds, average rate= (9.972*10-3-1.153*10-2)/(100-0)= -1.6*10-5M/usec

between 200 and 300 sec, average rate= (8.183*10-3-8.777*10-3)/(300-200)= -5.94*10-6M/usec
