What is the rate of reaction and the order of reaction if the mechanism of the reaction is, `2NO + H_(2) to H_(2) O_(2)` (slow reaction),
`H_(2) O_(2) + H_(2) to 2H_(2) O` (fast reaction)

Text Solution

Verified by Experts

We know, the slowest step is the rate determining step. Hence, the rate of the reaction `=k [NO]^(2) [H_(2) ]^(1)`
`therefore` Order of the reaction `= 2+1=3`
