Give the mechanism for the decomposition reacton of `H_(2)O_(2)` in alkaline medium catalysed by `I^(-)` ions. |
|
Answer» Chemical equation of decomposition of `H_(2) O_(2)` in alkaline medium is `2H_(2) O_(2) overset(I^(-))underset("Alkaline medium")to2H_(2)O+O_(2)` Mechanism : `to` It is a first order reaction w.r.t. both `H_(2)O_(2),I^(-)` `to` This reaction takes place is two steps `i) H_(2)O_(2)+ I^(-) to H_(2)O +IO^(-)` `ii) H_(2)O_(2)+IO^(-) to H_(2)O +I^(-) +O_(2)` |
