Answer the following problem <b>WITHOUT</b> using 5 % rule then again <b>With</b> using 5% rule.<br> <br> <br> At 250°C, the Equilibrium constant for the reaction :<br> <br> 1 <nowiki>PC</nowiki>l<sub>5 (g)</sub> <==> 1 <nowiki>PC</nowiki>l<sub>3 (g)</sub> + 1 <nowiki>C</nowiki>l<sub>2 (g)</sub> K = 2.15<br> <br> If the <nowiki>PC</nowiki>l<sub>5 (g)</sub> was initially the only gas present in the reaction vessel at 0.012500 atm, calculate the partial pressure of all the gases after equilibrium has been reached.<br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> <br> Book Answer:<br> p(<nowiki>PCl</nowiki><sub>3</sub>) = p(<nowiki>Cl</nowiki><sub>2</sub>) = 0.0125 atm, p(<nowiki>PCl</nowiki><sub>3</sub>) = 7.3E-5 atm<br> <br>
