Answer:
![rate=k[UO_2^+]^2[H^+]](https://img.qammunity.org/2021/formulas/chemistry/college/lwqtg9lhjlrhimf9n71w5dyj15f9dkb7x1.png)
Step-by-step explanation:
Rate law says that rate of a reaction is directly proportional to the concentration of the reactants each raised to a stoichiometric coefficient determined experimentally called as order.
The balanced chemical reaction is:
![rate=k[UO_2^+]^n[H^+]^m](https://img.qammunity.org/2021/formulas/chemistry/college/avbacap9lot17i9st4tj3szrxbdfx6kwqi.png)
where k = rate constant
n = order with respect to
= 2
m = order with respect to
= ?
n+ m = 3
2+ m = 3
m = 1
Thus m = order with respect to
= 1
