can the iodidecatalyzed decomposition of H202 occur by a sin

can the iodide-catalyzed decomposition of H202 occur by a single step mechanism? why or why not?

Solution

iodized catalyzed decomposition of H₂O₂ occur in two steps

H₂O₂+I^-=H₂O+OI^-

H₂O₂+OI^-=H₂O+O₂+I^-

here iodine is a catalsyt ,in one step iodide is consumed and in another step iodide is produced.

so one step mechanism is not possible.
