Answer:
replacement
Explanation:
Chemical reaction can be classified into various forms like decomposition reaction, replacement reaction, oxidation reaction, combustion reaction , synthesis reaction etc.
The best model that fits this scenario of substituting a player on the pitch is the replacement reaction.
A replacement reaction occurs when element switched ion in a compound. A replacement reaction occurs when element displace another element in it compound. The very reactive non metal element will displace another less reactive non metal element in it compound while a more reactive metal element will replace a less reactive metal element from it compound. An example is when fluorine replace Bromine in it compound or when Na replace hydrogen in it compound.
Na + HCl → NaCl
