(b).

Observe the graph:

The end behavior of the graph indicates that as the concentration of the catalyst solution is increased , the rate of  chemical reaction approaches 

Support numerically :

Construct a table that shows the values to investigate the function values as of  increases. 

Observe the table.

As the concentration of the catalyst solution is increased, the rate of chemical reaction approaches .
