The reaction , X + 2Y + Z rarr N occurs ...

The reaction , `X + 2Y + Z rarr N` occurs by the following mechanism
(i) `X+Y hArr M` (very rapid equilibrium)
(ii) `M + Z rarr O` (slow)
(iii) `O + Y rarr N` (very fast)
What is the rate law for this reaction

A

Rate `= k[Z]`

B

Rate `= k [X] [Y]^(2) [Z]`

C

Rate `= k[N]`

D

Rate `= k[X] [Y][Z]`

Text Solution

Verified by Experts

The correct Answer is:
D
`K_( c) = ([M])/([X][Y]) rArr [M] = KC [X][Y]`
Rate `= k^(-1)[M][Z] = K' KC [X] [Y][Z]`
`= K[X][Y][Z]`
