Question
At high temperatures, bromine molecules can dissociate into bromine atoms. For the reaction:

\[ \text{Br}_2(g) \rightleftharpoons 2 \text{Br}\cdot(g) \]

\[ K_p = 2.48 \times 10^{-3} \text{ at } 1650^\circ \text{C}. \]

A 5.00 L vessel at \( 1650^\circ \text{C} \) is filled with \(\text{Br}_2(g) \) at an initial pressure of 7.00 atm and allowed to come to equilibrium. What will be the pressure (in atm) of \(\text{Br}\cdot(g) \) at equilibrium?

### Explanation:

**Equation in Context:**
- The reaction describes the dissociation of bromine gas (\( \text{Br}_2 \)) into bromine atoms (\( \text{Br}\cdot \)).
- The equilibrium constant (\( K_p \)) is given as \( 2.48 \times 10^{-3} \) at a temperature of \( 1650^\circ \text{C} \).

**Calculation Steps:**
- To find the pressure of bromine atoms (\( \text{Br}\cdot \)) at equilibrium, use the equilibrium expression derived from \( K_p \).

**Graph or Diagram:**
- The image contains a virtual calculator on the right side, showing buttons for numerical input and pressure unit "atm" at the top.
