Question

A higher concentration of molecules causes a faster chemical reaction. This is known as _____.

Answer 1

Chemical equilibrium, because all reaction speed in an equilibrium would shift towards the side with less concentration of molecules.

Answer 2

Law of mass action

Step-by-step explanation:

According to the law of mass action, the rate at which a chemical reaction takes place depends on the concentration of the reactants. The higher the concentration of the reactants the higher will be the rate of reaction and thus more product will be formed

Or in other way it can be said that the rate of formation of any product through any chemical reaction is directly proportional to the concentration of the reactant.
