Answer:
To determine the rate law of the given reaction, we need to identify the rate-determining step of the reaction.
As per the given scheme, the rate-determining step is the conversion of HA and H+ to HAN+.
The rate law of the reaction can be expressed as:
Rate = k[HA][H+]
Where k is the rate constant of the reaction.
Therefore, the rate law of the acid-catalysed reaction, in which HA goes to products, is given by:
Rate = k[HA][H+]
