Because it increases the probability of collisions
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.
One can increase the rate of a chemical reaction by increasing the temperature, concentration of reactants, surface area of reactants, or using a catalyst.
raising the temperature of the reactants, by increasing their surface area, by increasing the concentration of reactants, by stirring the reactants, or by adding a catalytic agent can increase reaction rates
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.
Combining the reactants at a lower temperature. Reducing the concentration of reactants. Grinding one of the reactants into a powder. Removing the catalyst.

One can increase the rate of a chemical reaction by increasing the temperature, concentration of reactants, surface area of reactants, or using a catalyst.
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.

For most reactions which involve liquids or gases, increasing the concentration of the reactants also increases the rate of reaction. This is because the number of effective collisions are also increased which speeds up the reaction.
The kinetic energy of the reactants. By increasing the concentration, there are more reactant particles available for the reaction, and increasing the temperature increases the kinetic energy so the reactants come in contact more often, and the reaction rate increases.
