Give the example for a zero order reaction.

Explanation

(i) Photochemical reaction between `H_(2)` and `CI_(2)`
`H_(2) O_((g)) rArr N_(2) + (1)/(2) O_(2) `
(ii) Decomposition of N20 on hot platinum surface
(iii) lodination acetone in acid medium is zero order with respect to iodine
`CH_(2) COCH_(2) + I_(2) overset(H^(+))(to) ICH_(2) COCH_(2) +HI`
`Rate = k [CH_(2) COCH_(3)] [H^(+)]`
