The rate of a chemical reaction is directly proportional to the product of active masses of the reactants, it is referred to as:
Correct answer: B. Law of mass action
- A. Law of conservation of energy
- B. Law of mass action
- C. Law of conservation of mass
- D. Active mass law
Explanation
The law of mass action states the rate of chemical reaction is directly proportional to the product of the reactant concentration values. This law gives a formula for the equilibrium constant:Kc={C}^c {D}^d/{A}^a {B}^b

About Reaction Kinetics
Reaction kinetics relates reaction rate to concentration, temperature, surface area and catalysts. Questions cover rate laws, reaction order, rate constants, activation energy and the activated complex, including how a catalyst lowers the activation energy without changing the overall energy change or equilibrium position.
