Question: In a reaction A → B, if the rate of reaction doubles when the concentration of A is doubled, what is the order of the reaction with respect to A?

Options:

  1. Zero order
  2. First order
  3. Second order
  4. Third order

Correct Answer: First order

Solution: 

If the rate doubles when the concentration of A is doubled, the reaction is first order with respect to A.

Questions & Step-by-Step Solutions

In a reaction A → B, if the rate of reaction doubles when the concentration of A is doubled, what is the order of the reaction with respect to A?
  • Step 1: Understand that the reaction is A → B.
  • Step 2: Know that the rate of reaction depends on the concentration of A.
  • Step 3: When the concentration of A is doubled, observe that the rate of reaction also doubles.
  • Step 4: This means that if you increase the concentration of A, the rate increases in a linear way.
  • Step 5: In chemistry, if doubling the concentration of a reactant doubles the rate of reaction, it indicates that the reaction is first order with respect to that reactant.
  • Step 6: Therefore, conclude that the order of the reaction with respect to A is first order.
  • Reaction Order – The order of a reaction indicates how the rate is affected by the concentration of reactants.
  • Rate Law – The rate law expresses the relationship between the rate of a reaction and the concentration of its reactants.
