Because it increases the probability of collisions
when you increase the concentration of the reactants the particles move quicker resulting in more collision. This makes the rate of the reaction to increase.
Even if the particles are moving at the same speed, with a higher concentration of reactants, there is a higher probability that a reactant molecule will collide with another reactant molecule rather than with a water molecule.
The more the concentration, the more particles that will be togther and that would make a better collisions between particles
more possible collisions
The concentration of reactants is changed.
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.
The reaction rate increase with reactants concentration.
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
increasing surface area addition of 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
Increasing the concentration of the reactants the rate of reaction increase.
The concentration of reactants is changed.
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.
The reaction rate increase with reactants concentration.
