Answer:
Explanation:
Hello,
In this case, for the given decomposition of phosphorous pentachloride:
As the equilibrium constant is and the initial concentration of phosphorous pentachloride is:
Hence, by writing the law of mass action equation:
We must introduce the change occurring due to the reaction extent and the concentrations at equilibrium (ICE table methodology):
Thus, solving for we obtain:
In such a way, the equilibrium concentration of phosphorous pentachloride results:
Finally, the percent decomposition is computed by:
Best regards.
