What is the relationship between concentration and rate of reaction?
grigory [225]
<h3><u>Answer;</u></h3>

Directly proportional

<h3><u>Explanation;</u></h3>
  • <em><u>Concentration is one of the factors that determine the rate of a reaction. Reaction rates increases with increase in the concentration of the reactants, which means they are directly proportional.</u></em>
  • An increase in the concentration of reactants produces more collisions and thus increasing the rate at which the reaction is taking place. Therefore, <u>Increasing the concentration of a reactant increases the frequency of collisions between reactants and will cause an increase in the rate of reaction.</u>
