Consider some facts about decomposition of `H_(2)O_(2).`
It is catalysed by iodide ion in acidic medium.
It is second order reaction with respect to both `H_(2)O_(2).andI^(-1).`
Rate equation of this particular reaction will be
`Rate=(-d[H_(2)O_(2)]^(2))/(dt)=k[H_(2)O_(2)]^(2)[I^-]`
It completes in two steps and both steps are unimolecular elementary reactions.
Which of the above written facts are correct, regarding decomposition of `H_(2)O_(2)?` Choose the correct option.
A. I and II
B. II and III
C. III and IV
D. I and Iv

Correct Answer - D
Decomposition of `H_(2)O_(2)`
`2H_(2)O_(2)overset(1^(-))underset("Alkaline medium")rarr2H_(2)O+O_(2)`
Rate equation is rate `(-d[H_(2)O_(2)])/(dt)=k[H_(2)O_(2)][1^(-)]`
This reaction is first order w.r.t. both `H_(2)O_(2) and 1^(-).` It makes place in two steps and both are bimolecular elementary reactions.
