Question
![A chemical engineer is studying the following reaction:
\[ \text{4HCl}(g) + \text{O}_2(g) \rightarrow \text{2H}_2\text{O}(g) + \text{2Cl}_2(g) \]
At the temperature the engineer picks, the equilibrium constant \( K_p \) for this reaction is 0.039.
The engineer charges ("fills") four reaction vessels with hydrogen chloride and oxygen, and lets the reaction begin. He then measures the composition of the mixture inside each vessel from time to time. His first set of measurements are shown in the table below.
Predict the changes in the compositions the engineer should expect next time he measures the compositions.
