According to law of mass action rate of a chemical reaction is proportional to
Options
(a) concentration of reactants
(b) molar concentration of reactants
(c) concentration of products
(d) molar concentration of products
Correct Answer:
molar concentration of reactants
Explanation:
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”. Active mass = molar concentration of the substance.
