According to the concept of law of mass action, the rate of a chemical reaction is proportional to

Options

  1. AConcentration of reactants
  2. BConcentration of products
  3. CProduct of activemasses of reactant raised to a power equal to their stoichiometry coefficient
  4. DMolar concentration of products

Correct answer

C. Product of activemasses of reactant raised to a power equal to their stoichiometry coefficient

Step-by-step solution

According to law of mass-action, “at a given temperature, the rate of a reaction at a particular instant is proportional to the product of the active masses of the reactants at that instant raised to powers which are numerically equal to the numbers of their respective molecules in the stoichiometric equation describing the reaction”.
