Hello! I have 2 questions that's had me stumped for four days now and I can't figure out how to do it. I am absolutely terrible with rates and equations so any help will be gladly appreciated. The experiment is the Iodine Clock reaction varying the concentration of iodine used.
"the rate equation for the reaction is: rate= k[I-(aq)][S2O8^2-(aq)]
Work out the concentration of S2O8^2- that you used in each of your experiments. "
-I have the concentration of Iodine used and initial rate from my experiments but how do I use it here?
"Rearrange the rate equation so that you can find the rate constant, with units, for the reaction. You will need both the concentration of S2O8^2- Ions and the gradient of your graph."
- Again how do I use my data to solve this question?
Thanks in advance!!!

Just place in the known conc. and initial rate to find out S2O8 2-
I'm not sure what u mean by the graph?
I thin know for the rate constant you do 1/t (t=time in seconds)Last edited by Hazel99; 14-10-2016 at 15:53.
