Q
Q: 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?
Solution: If the rate doubles when the concentration of A is doubled, the reaction is first order with respect to A.
Steps: 6
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.
