Experiment 1 : Rate1 = k [S2O82-]q [I-]r
Experiment 2: Rate2 = k (2[S2o82-])q [I-]r = 2q x rate1
Experiment3: Rate3 = k [S2O82-]q (2[I-]r = 2r x rate1
1) What is the initial rates of experiment 1,2,and 3 from ?[S2O8 2-]/?t ?
2) Obtain the reaction orders with respect to the S2O82- and I- ions.
3) What is the correct equation?
4) Calculate the initial concentration of the S2O82- and I- ions in experiment 1,2,and 3
5) Calculate the rate constant in experiment 1,2,and 3 and obtain the mean. Give the correct units
how do i start the calculation please help me
