Questions & Step-by-Step Solutions
For a reaction that is first order in A and second order in B, what is the overall order of the reaction?
Step 1: Identify the order of the reaction with respect to each reactant.
Step 2: Note that the reaction is first order in A, which means the order for A is 1.
Step 3: Note that the reaction is second order in B, which means the order for B is 2.
Step 4: Add the orders together: 1 (for A) + 2 (for B).
Step 5: Calculate the total: 1 + 2 = 3.
Step 6: Conclude that the overall order of the reaction is 3.
Reaction Order – The overall order of a reaction is determined by summing the individual orders of each reactant.
First Order Reaction – A reaction is first order in a reactant if the rate of reaction is directly proportional to the concentration of that reactant.
Second Order Reaction – A reaction is second order in a reactant if the rate of reaction is proportional to the square of the concentration of that reactant.
