Q: For 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?

Solution: If doubling the concentration of A doubles the rate, the reaction is first order with respect to A.

Steps: 7

Step 1: Understand that the rate of a reaction depends on the concentration of the reactants.
Step 2: Identify the reaction: A → B.
Step 3: Note that the rate of reaction is how fast A turns into B.
Step 4: Recognize that if the concentration of A is doubled, we are changing the amount of A available for the reaction.
Step 5: Observe that when the concentration of A is doubled, the rate of reaction also doubles.
Step 6: This means that the rate is directly proportional to the concentration of A.
Step 7: In chemical kinetics, if doubling the concentration of a reactant doubles the rate, the reaction is first order with respect to that reactant.
