Answer

Explanation:

Step1: Write the reaction quotient expression

$$Q = \frac{[\text{HI}]^2}{[\text{H}_2][\text{I}_2]}$$

Step2: Substitute the given molar concentrations

$$Q = \frac{(3.50)^2}{(0.100)(0.200)}$$

Step3: Calculate the numerator and denominator

$$Q = \frac{12.25}{0.0200}$$

Step4: Perform the final division

$$Q = 612.5$$

Answer:

613
