if for the reaction, ax + by --> products, the rate law is determined to be r = kx^1y^2, then the order of the reaction is which of the following?
4
3

Explanation:

Step1: Recall the formula for reaction order

The order of a reaction is the sum of the exponents in the rate law.

Step2: Calculate the sum of exponents

Given the rate law \( r = k[X]^1[Y]^2 \), the sum of exponents is \( 1 + 2\).
\(1+2=3\)

Answer:

3
