Rate₁ = k [A]ⁿ[B]ᵐ. If Rate₁ = 4 × k [A]²[B]², determine the relationship between y and 2y.

1. y = 2
2. y = 1
3. y = 0
4. y = -2

Correct answer: y = 1

Solution

The given rate law suggests that the reaction order with respect to A is 2 and with respect to B is 2. Thus, the overall order is 4, and y = 1 satisfies the relationship between y and 2y.
