Chemical Engineering Thermodynamics (MCQs)

The rate at which a substance reacts is proportional to its active mass and the rate of a chemical reaction is proportional to the product of active masses of the reacting substances. This is the

  • A. Lewis-Randall rule
  • B. Statement of Vant-Hoff equation
  • C. Le-Chatelier’s principle
  • D. None of these
Answer: Option D.
Explanation: 
The given statement is law of mass action which states that the rate of chemical reaction is directly proportional concentration of species involved in reaction. Concentration involved in reaction = active mass.
