It means that there will be more particles of the reactants in the vessel, so they are more crowded and collisions of the right energy are more likely.
or
collisions of the right energy are more likely.
By increasing the concentration of reactants, the rate of reaction increases. This is because there are more particles in a given volume of fluid. This means that the reactions will take place faster between the substances.
Increasing the concentration of a reactant normally increases the rate of reaction. However, if the reaction rate is controlled under the conditions considered by the concentration of a different reactant, the reaction rate may not change when the concentration of some other reactant is increased.
-Decrease heat in the reactant -add more of the given substance to the reactants
It will increase the reaction rate or leave it the same, depending on whether the particular reactant added is one that is limiting the reaction rate before the addition.
Increasing the concentration of reactants increases the rate of forward reaction
Collisions of the right energy are more likely
The reaction rate increase with reactants concentration.
Because it increases the probability of collisions
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 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.
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
I dont know really
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
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.

decrease in reactants and increase in products
Concentration of products would increase in order to attain equilibrium in the system again.For example:H2CO3 --> H+ + HCO3-K= ([H+][žHCO3-])/([H2CO3])K is constant for this process, so if you increase the concentration of reactants (H2CO3), in order for K to stay the same, concentration of products (H+, HCO3-) would also have to increase.It's part of Le Chatelier's principle: "If a chemical system at equilibrium experiences a change in concentration, temperature, volume, or partial pressure, then the equilibrium shifts to counteract the imposed change and a new equilibrium is established."So, in your case, adding more reactant would cause equilibrium to shift to the right (toward products), and therefore, their concentration would increase so that new equilibrium could be established.
