increasing the concentration in a rate of reaction makes the reaction take place faster because if there is more initial particles then there is more particles to react
Increasing the concentraion the reaction rate increase.
Rate dependence on the concentration of reactants refers to how the rate of a reaction is affected by changes in the concentration of the reactants. The rate of many reactions is directly proportional to the concentration of the reactants, following a rate law equation. Increasing the concentration of reactants generally leads to an increase in the rate of the reaction, while decreasing the concentration typically results in a slower reaction rate.
In general (but not always), the reaction rate will increase with increasing concentrations. If the reaction is zero order with respect to that substance, then the rate will not change.
One can increase the rate of a chemical reaction by increasing the temperature, concentration of reactants, surface area of reactants, or using a catalyst.

The effect of concentration of reactants on rate of reaction depends on the ORDER of the reaction. For many reactions, as the concentration of reactants increases, the rate of reaction increases. There are exceptions however, for example a zero order reaction where the rate of reaction does not change with a change in the concentration of a reactant.
Changes in concentration affect the rate of reaction by impacting the rate constant, k, in the rate law equation. Increasing reactant concentrations often leads to a higher rate of reaction, while decreasing concentrations can slow the reaction down. The rate law shows how the rate is related to the concentrations of reactants.
Increasing temperature, increasing concentration of reactants, using a catalyst, and increasing the surface area of the reactants can all increase reaction rate by providing more energy for collisions between reactant molecules.
Because the concentration is directly proportional to the rate of reaction (the rate will increase but k will remain the same), with an increase in concentration the activation energy will stay because the activation energy does not account for the concentration.
