They can all affect the rate of a chemical reaction.
When the concentration of the reactant is decreased, the rate of chemical reaction go slow.
The concentration of a pure liquid change throughout the course of a reaction decreases. This is because the substance is no longer pure.
rate laws a+the higher the concentration = more particles = higher chance of a collision happening = higher/faster reaction rate
Usually, increasing concentration of reactants increases the rate of reaction, but increasing concentrations of products reduces the rate of reaction. However, if one reactant is already present in large stoichiometric excess over another, increasing the concentration of that reactant may not increase the rate of reaction at all, and if the free energy of reaction is large enough in magnitude, increasing the concentration of products may not reduce the rate of reaction at all.
The exponents determine how much concentration changes affect the reaction rate
Reaction rate increase when the concentration increase.

That depends on the order of the reaction. If the reaction is zero order with respect to a reactant, then changing the concentration will have no effect on rate. If it is first order, then doubling the concentration will double the rate. If it is second order, then doubling the concentration will quadruple the rate.
The exponents determine how much concentration changes affect the reaction rate
the rate is affected by concentrations raised to the power of an exponent
increasing the concentration increases the rate of the reaction
increasing the concentration increases the rate of the reaction
increasing the concentration increases the rate of 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.
Increasing the concentration of the reactants the rate of reaction increase.
