The rate of a chemical reaction can be measured as the rate of appearance of any of the products or as the rate of disappearance of any of the reactants. these relative rates of reaction are related through the stoichiometry of the overall reaction. for example, the rate of the reaction shown below can be determined by measuring the initial rate of disappearance of i-, -d[i-]/dt. clo3-(aq) + 9i- (aq)+ 6 h+ (aq) → 3i-3 (aq) + cl-(aq) + 3h2o if the initial rate of disappearance of i- under a given set of experimental conditions is 81.1 x 10-3 m/s then what is the rate of disappearance of clo3- under those same experimental conditions? enter your answer with units.

13. calculate the initial concentration (before precipitation) of carbonate ions after the addition of each 0.05 ml of solution b to the 1.00 l beaker of solution a. divide the work among group members and write the answers in the table in model 3. assume the volume change as solution b is added is negligible. 14. notice the initial concentrations of zn2+ - and cu2+ in the table in model 3. a. explain how these were obtained from the data in model 2. b. as solution b is added and precipitates form, do these initial concentrations change? 15. use the data in model 2 to indicate the presence of precipitate (either znco3 or cuco3) after each 0.05 ml addition of solution b in model 3. 16. use the initial concentrations of carbonate ions and zinc ions to calculate the reaction quotient, qsp for the zinc carbonate scenarios in model 3. divide the work among group members and write the answers in the table in model 3. 17. use the initial concentrations of carbonate ion and copper(ii) ions to calculate the qsp for the copper(ii) carbonate scenarios in model 3. divide the work among group members and write the answers in the table in model 3.
