Discuss briefly the effect of concentration on the rate of a reaction.

Explanation

Relationship between rate of chemical reaction and concentration is given by Guldberg and Waage. The relation is called as law of mass action. It states that the rate of a chemical reaction is directly proportional to the product of the molar concentration of the reacting species, raised to the power equal to their coefficients.
Consider a general equation, aA + bB + cC `to` products
According to the law of mass action rate of reaction `prop [A] %( a ) [B] ^(b ) [C] ^(c) [B] ^(b [ C ] ^(c)`
Where k = rate constant.
