this system has an equilibrium constant of 50.5 at 448°c: h₂(g) + i₂(g) → 2hi(g). what is the reaction quotient, q, for this system when h₂=0.200 m, i₂=0.100 m, and hi=3.00 m? how does q compare to k_eq? q > k_eq q < k_eq q = k_eq
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
Substitute $[H_2]=0.200\ M$, $[I_2]=0.100\ M$, and $[HI]=3.00\ M$ into the formula: $Q=\frac{(3.00)^2}{0.200\times0.100}=\frac{9.00}{0.0200}=450$.
Step3: Compare $Q$ and $K_{eq}$
Given $K_{eq} = 50.5$. Since $450>50.5$, we have $Q > K_{eq}$.
Answer:
The reaction - quotient $Q = 450$ and $Q>K_{eq}$
