Question
### Chemical Equilibrium Problem

Be sure to answer all parts. The equilibrium constant (\( K_c \)) for the formation of nitrosyl chloride, an orange-yellow compound, from nitric oxide and molecular chlorine is given by the reaction:

\[ 2NO(g) + Cl_2(g) \leftrightarrow 2NOCl(g) \]

The equilibrium constant (\( K_c \)) is \( 5 \times 10^5 \) at a certain temperature. In an experiment, \( 8.40 \times 10^{-2} \) moles of \( NO \), \( 2.10 \times 10^{-3} \) moles of \( Cl_2 \), and 7.60 moles of \( NOCl \) are mixed in a 1.10 L flask.

**Question:**
What is \( Q_c \) for the experiment?

**Answer:**
\[ Q_c = 9.823 \times 10^{-5} \] 
(Enter your answer in scientific notation.)

**Follow-up Question:**
In which direction will the system proceed to reach equilibrium?

**Options:**
1. The reaction is at equilibrium.
2. The reaction will proceed to the left. (Checked option)
3. The reaction will proceed to the right.

**Explanation of Graphs/Diagrams:**
- The diagram includes a boxed section where the calculation of \( Q_c \) is displayed using scientific notation: \( 9.823 \times 10^{-5} \).
- Below the calculation, there are multiple-choice options for identifying the direction in which the reaction will proceed to reach equilibrium. The correct option, “The reaction will proceed to the left,” is indicated by a checkmark.

This problem helps students understand how to calculate the reaction quotient (\( Q_c \)) and predict the direction of the reaction based on the comparison between \( Q_c \) and the equilibrium constant (\( K_c \)).
