H2o2 and ki reaction

WebThe first step of H2O2 with I- (iodide not iodine) to make H2O and IO- is the rate limiting step making the rate law: rate=k [H2O2] [I-]. First order in the reactant and first order in the catalyst and second order overall. 2 I -> I2 + 2 H2O, that's a little trickier. It's multi-step, and I don't really know what the rate law is. WebMay 1, 2014 · Is there a complete list of all the half equations for $\ce{H2O2}$ - both oxidation and reduction, in acidic and alkaline conditions? I've looked on the internet but can't seem to find a list with all of them. These are my first attempts: $\ce{H2O2 + 2e^- -> 2OH^-}$ (in alkaline conditions) $\ce{H2O2 + 2H^+ + 2e^- -> 2H2O}$ (in acidic conditions)
