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 reaction rate increase with reactants concentration.
Either (or both) an increase in the reactants or temperature will increase the rate of a chemical reaction.
decrease in reactants and increase in products
Increasing the temperature of the reactants can increase the rate of the chemical reaction.
The more concentrated the solution of reactants, the more the reaction wants to push right making more products.Same goes vice-versa; if there's more products, then the reaction will push left producing more reactants.
Increasing the concentration of the reactants the rate of reaction increase.
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 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.
