Answer:
A higher concentration of a catalyst will speed up the reaction rate.
A solution that has a high amount of solute/concentration in the solvent is concentrated because if there is a lot of solute compared to the solvent, then the ratio of solute to solvent is higher, and thus the concentration is higher too.
Hope this helps!
