Which of the following statements represents rate of reaction?

Options

  1. AChange in temperature per unit time
  2. BChange in concentration of reactants or products per unit time
  3. CChange in volume of the reaction mixture
  4. DChange in color of the solution

Correct answer

B. Change in concentration of reactants or products per unit time

Step-by-step solution

The rate of a chemical reaction is defined as the change in the concentration of any one of the reactants or products per unit time. Mathematically, Rate = C t , where C is the change in concentration and t is the time interval. Answer: Change in concentration of reactants or products per unit time
