"Increasing the concentration of a reactant increases the rate of a reaction by increasing the rate constant in the forward direction"
Would this statement be false?? If so, could someone explain why that is?

This statement should be false because the rate constant doesn't change based on concentration of reactants. The rate in total does change, but the rate constant changes based on the Arrhenius equation, which involves temperature, activation energy, and collision rate, but NOT concentration.
