Question

Be sure to answer all parts. Give the individual reaction orders for all of the following substances and the overall reaction order from the following rate law: Rate=kA2B

a) Order of A: 2, Order of B: 1, Overall Order: 3
b) Order of A: 1, Order of B: 2, Overall Order: 3
c) Order of A: 2, Order of B: 2, Overall Order: 4
d) Order of A: 1, Order of B: 1, Overall Order: 2

Answer 1

The correct reaction orders from the given rate law Rate = kA2B are 2 for reactant A, 1 for reactant B, and 3 for the overall reaction order.

Step-by-step explanation:

The given rate law is Rate = kA2B. From this rate law, we can deduce the following:

• The order of reactant A is 2, because the rate is proportional to the square of the concentration of A.
• The order of reactant B is 1, as the rate is directly proportional to the concentration of B.
• The overall reaction order is the sum of the individual orders, which is 3 (since 2 + 1 = 3).

Therefore, the correct answer out of the given options is: Order of A: 2, Order of B: 1, Overall Order: 3.
