decrease in reactants and increase in products
The concentration of reactants is greater than the concentration of reactants at equilibrium. The concentration of products is less than the concentration of products at equilibrium
First read this to understand equilibrium: if the point of equilibrium moves to the left there will be more reactants than products. If the point of equilibrium moves to the right there will be more products than reactants. Le Chatelier's principle states that whatever you do to the reaction, the reaction will try and reverse the effects. Eg: heat it, and it will try and cool it down. ANSWER: If you increase the concentration of the reactants (left side), according to Le Chatelier's principle the reaction will try and get rid of the extra reactants, so it will decrease the concentration of reactants. This means the position of equilibrium will move to the right, so more products will be formed.
need not be..equilibrium constant is just a ratio of relative concentrations of products (multiplication of concentration in case of more than one products) to the concentration of reactants (multiplication of concentrations of reactants in case of more than one reactants)..the equilibrium concentration can be a very small number or can be a very number as well depending upon the relative concentrations of reactants and products..Unity equilibrium constants is just a special case which shows that the concentrations of products and reactants are equal..
The "amounts" of reactants and products DO change in a reversible reaction. What doesn't change is the concentration of these reactants and products AT EQUILIBRIUM. And also what does not change is the total mass of the system.
the equilibrium constant
The reactants concentration is equal to products concentration.
The concentration of reactants is greater than the concentration of reactants at equilibrium. The concentration of products is less than the concentration of products at equilibrium
The concentration of reactants is less than the concentration of reactants at equilibrium. The concentration of products is greater than the concentration of products at equilibrium.

increasing the concentration increases the rate of the reaction

The concentration of reactants and products remain constant.
the equilibrium constant
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.
No, the equilibrium constant is independent of concentration as long as the ratio of products and reactants remains as is. It can be effected by anything that would influence the ratio of products and reactants, such as changes in temperature or the addition of a catalysis.
