What will be the order of a reaction if its rate is expressed as
Rate = $k[A]^{1/2}[B]^{3/2}$
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 2
Core concept
Order of reaction = sum of powers of concentration terms in rate law.
Stepwise Calculation
Rate = k [A]¹ᐟ² [B]³ᐟ²
Order with respect to A = 1/2
Order with respect to B = 3/2
Total Order
Total order = 1/2 + 3/2
Total order = 4/2
Total order = 2
