Question

A chem ngineer is studying the following reaction:
4 HCl(g) + O₂(g) → 2H₂O(g) + 2Cl₂(g)
At the temperature the engineer picks, the equilibrium constant K for this reaction is 0.17.
P
The engineer charges ("fills") four reaction vessels with hydrogen chloride and oxygen, and lets the reaction begin. She then measures the composition of the
mixture inside each vessel from time to time. Her first set of measurements are shown in the table below.
Predict the changes in the compositions the engineer should expect next time she measures the compositions.

Expert Solution

Step 1: Relation between reaction quotient and equilibrium constant

Answer:

Relation between reaction quotient Q_P and equilibrium constant K_P is shown below:

1. When $Q subscript P equals K subscript P$ reaction mixture is at equilibrium.

2. When $Q subscript P less than K subscript P$ reaction mixture is not be at equilibrium and to establish the equilibrium reaction will move forward so that Q_P can increase and become equal to K_P.

3. When $Q subscript P greater than K subscript P$ reaction mixture is not at equilibrium and to establish the equilibrium reaction will move in reverse direction so that Q_P can decrease and become equal to K_P.

Given that:

$straight K subscript straight P equals 0.17$
