Answer:

After millions of years underground, the compounds that make up plankton and plants turn into fossil fuels. Plankton decomposes into natural gas and oil, while plants become coal. Today, humans extract these resources through coal mining and the drilling of oil and gas wells on land and offshore.

The equilibrium constant, Kc, for the following reaction is 83.3 at 500 K. PCl3(g) Cl2(g) PCl5(g) Calculate the equilibrium conc
Alik [6]

Answer:

[PCl_3]=[Cl_2]=0.068M

[PCl_5]=0.385M

Explanation:

Hello!

In this case, since the equilibrium expression for the considered equation is:

Kc=\frac{[PCl_5]}{[Cl_2][PCl_3]}

Which can be written in terms of the reaction extent and the ICE chart and the initial concentrations of 0.453 M as shown below:

83.3=\frac{x}{(0.453M-x)(0.453M-x)}

We can solve for x as follows:

x=0.385M

In such a way, we obtain the following concentrations at equilibrium:

[PCl_3]=[Cl_2]=0.453M-0.385M=0.068M

[PCl_5]=0.385M

Best regards!
