Final answer:
The syrup is the recommended form of paracetamol for administering to an infant.
Step-by-step explanation:
To administer paracetamol to an infant, it is recommended to use the syrup rather than the tablet. The choice is not connected to the rate of reaction in chemistry. Infant formulas, such as syrup, are specifically designed to be easier to swallow and digest for infants. Tablets may pose a choking hazard and are harder for infants to consume. Therefore, the syrup is the safer and more appropriate option for administration to an infant.
