The decomposition of hydrogen peroxide in the presence of potassium iodide is believed to occur by the following mechanism:
step 1 slow: H2O2 + I^- = H2O + OI^-
step 2 fast: H2O2 + OI^- = H2O + O2 + I^-
1) What is the equation for the overall reaction? Use the smallest integer coefficients possible.
I am not sure about this part.
2) Which species acts as a catalyst? Enter formula if there is one.
I think that I^- is the catalyst.
3) Which species acts as a reaction intermediate?
I think the H2O2 is the reaction intermediate.
4) Complete the rate law fot the overall reaction that is consistent with this mechanism.
I know that it would be k but I am not sure what it is.
Thank you for your help!!
