Question

\\2\text{no}(\text{g}) + \text{o}_2(\text{g}) \
ightleftharpoons 2\text{no}_2(\text{g})\\
\\k = 1.5 \times 10^{-10} \quad q = 0.19\\
what will happen to the reaction based on the relationship of q vs. k?

1. make more reactants because \\(q < k\\).
2. make more reactants because \\(q > k\\).
3. make more products because \\(q < k\\).
4. make more products because \\(q > k\\).
5. no change because \\(q = k\\).

enter the answer choice number.

<reasoning>

Compare the values of Q and K

Using the Reaction Quotient and Equilibrium Constant knowledge points
\[

$$\begin{aligned} &Q = 0.19 = 1.9 \times 10^{-1}\\ &K = 1.5 \times 10^{-10}\\ &1.9 \times 10^{-1} > 1.5 \times 10^{-10} \implies Q > K \end{aligned}$$

\]

Determine the direction of shift

Using the Chemical Equilibrium knowledge point
\[

$$\begin{aligned} &Q > K \implies \text{Excess products present}\\ &\text{Reaction shifts left to reach equilibrium}\\ &\text{Shift left} \implies \text{Make more reactants} \end{aligned}$$

\]

Match with the given options

Using the Chemical Equilibrium knowledge point
\[

$$\begin{aligned} &\text{Option 2 states: "Make more reactants because } Q > K\text{."} \end{aligned}$$

\]
