Answer

Explanation:

Step1: Write reaction quotient formula

The reaction quotient $Q$ for the reaction $H_2(g)+I_2(g)\rightleftharpoons 2HI(g)$ is given by $Q=\frac{[HI]^2}{[H_2][I_2]}$.

Step2: Substitute given concentrations

We are given $[H_2] = 0.100\ M$, $[I_2]=0.200\ M$ and $[HI]=3.50\ M$. Substituting these values into the formula, we get $Q=\frac{(3.50)^2}{0.100\times0.200}$.

Step3: Calculate the value of Q

First, $(3.50)^2 = 12.25$. Then, $0.100\times0.200=0.02$. So, $Q=\frac{12.25}{0.02}=612.5\approx613$.
