The acid catalysed ionisation of `gamma`-hydroxy butyric acid proceeds as a reversible reaction. Which is I order in both the forward and backward steps:
`underset("(Acid)")(A) underset(K_(1)) overset(K_(2))(hArr) underset("(Lactose)")(B)`
The rate `-(d[A])/(d t)` is given by:

Options

A. `K_(1)[A]`
B. `-K_(2)[B]`
C. `K_(1)[A]-K_(2)[B]`
D. `(K_(1)[A])/(K_(2)[B])`

Answer

C

Explanation

rate `= K[A] - K_(2)[B]`, This is reversible reaction.
