# Explanation:## Step1: Identify the Rate Law Formula### The rate law formula is given as
.## Step2: Substitute Given Values### Substitute the given values into the formula:
,
M,
M,
, and
. The formula becomes \( \text{rate} = 1.5 \cdot (1)^2 \cdot (3)^1 \).## Step3: Simplify the Expression### Simplify the expression to calculate the rate:
# Answer:### A. \( 4.5\ (\mathrm{mol} / \mathrm{L}) / \mathrm{s} \)
