I would point your studies towards collision theory.
It's not that a low concentration necessarily slows down a reaction, but that a low concentration will have a slower reaction rate than a higher concentration of reactants. A lower concentration means a lower number of reactants in solution, meaning it is less likely for the reactants to collide and create products. With a lot of reactants, it is much more likely for collisions to occur.
Yes, the rate constant can change with concentration in a chemical reaction.
An inhibitor decreases the reaction rate
Increasing the concentration of the reactants increases the rate of the reaction.

Inhibitor~a material used to decrease the rate of reaction
negative catalyst.
the rate is affected by concentrations raised to the power of an exponent
To calculate the initial rate of reaction in a chemical reaction, you measure the change in concentration of a reactant over a specific time interval at the beginning of the reaction. This change in concentration is then divided by the time interval to determine the initial rate of reaction.
The substance that slows down a chemical reaction is an inhibitor. Instead you could also call an inhibitor an anticatalyst.-anticatalyst `antee'katlist1. (chemistry) a substance that retards a chemical reaction or diminishes the activity of a catalyst
Decreasing the concentration of a reactant will typically decrease the rate of a chemical reaction, as there are fewer reactant molecules available to collide and form products. This is in line with the rate law, which often shows a direct relationship between reactant concentration and reaction rate.
A catalyst is a material that speeds up a chemical reaction by providing an alternative pathway with lower activation energy. Alternatively, an inhibitor is a material that slows down a chemical reaction by blocking the active sites on the reactant molecules, preventing them from coming together or reacting.
The first-order reaction formula used to determine the rate of a chemical reaction is: Rate kA, where Rate is the reaction rate, k is the rate constant, and A is the concentration of the reactant.
