Dr. Ken Etticks investigates the oxidation of iodide ion by arsenic acid in aqueous solution. The reaction is: 3I(aq)+H3AsO4(aq)+2H+(aq)I3(aq)+H3AsO3(aq)+H2O(l) During his experiment the following data were collected: [I]=2.78102M at t=60.0s, and [I]=1.42102M at t=80.0s Calculate the value of t[1] during this time interval. M/s What is the average rate of change of I3 during this time interval? M/s What is the average rate of change of H+during this time interval? M/s Calculate the average rate of reaction during this time interval. M/s
