Question

The rate of reaction can be calculated by calculating? 

Options
  • A

    Change in temperature

  • B

    Change in pressure

  • C

    Change in volume

  • D

    Change in concentration

Explanation

Rate is the change in concentration per unit time. When the reactant is used up that means that the reaction is taking place. Hence, as the reactant is used up we can determine the rate at which the concentration of the reactant is used up hence we can determine the rate of reaction.

This option is not correct.
