Unit of the rate constant depends upon the:

Correct answer: C. Order of reaction

  • A. Molecularity of reaction
  • B. Concentration terms
  • C. Order of reaction
  • D. Number of reactants

Explanation

The order of reaction indicates how the rate of a reaction depends on the concentration of reactants. The unit of the rate constant is directly related to the order of reaction. For example, if a reaction is first-order, the unit of the rate constant will be in terms of concentration per unit time.

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.
