<b>Remember: Need to Write Down First Balanced Chemical Reaction and Equilibrium Constant Expression</b><br> <br> 1. At 750degC, the following reaction reaches equilibrium in a 1-L container.<br> <center>1 H<sub>2(g)</sub> + 1 <nowiki>CO</nowiki><sub>2(g)</sub> <--> 1 H<sub>2</sub>O<sub>(s)</sub> + 1 <nowiki>CO</nowiki><sub>(g)</sub></center><br> At equilibrium, the 1-L flask contains 0.13moles hydrogen, 0.25moles carbon dioxide, and 0.57moles carbon monoxide. Calculate K<sub>eq</sub> for this reaction.<br> <br> <br> <br> <br> <br> <Br> <Br> <br> <br> <Br> <br> <br> <br> <br> <br> 2.For the reaction , 2 <nowiki>KClO</nowiki><sub>3(s)</sub> <--> 2 <nowiki>KCl</nowiki><sub>(s)</sub> + 3 O<sub>2(g)</sub> <br> K<sub>eq</sub> = 2.3E-4. What is the equilibrium concentration of oxygen (O<sub>2</sub>)? What about the concentration of <nowiki>KClO</nowiki><sub>3</sub> and <nowiki>KCl</nowiki>? <br> <br> <br> <br> <br> <br> <br> <Br> <Br> <br> <br> <br> <br> <Br> <br> <br> <br> <br> 3. For reaction 2 <nowiki>SO</nowiki><sub>2(g)</sub> + O<sub>2(g)</sub> <--> 2 <nowiki>SO</nowiki><sub>3(g)</sub><br> a 0.25-L container initially has 2.00 moles of <nowiki>SO</nowiki><sub>3</sub>. If 75% of this compound has reacted at equilibrium, what are the equilibrium concentration of all species and then calculated K (equilibrium constant)?<br> <br> <br> <br> <br> <br> <Br> <Br> <br> <br> <Br> <br> <br> <br> <br> 4. The reaction <nowiki>PCl</nowiki><sub>5(g)</sub> <---> <nowiki>PCl</nowiki><sub>3(g)</sub> + Cl<sub>2(g)</sub> has a K= 11.5. A 0.5-L gas vessel has one mole of <nowiki>PCl</nowiki><sub>5</sub>, what is the equilibrium concentration of all species?<b>For 2007-2008, do not do this question, Question 4, only for extra credit. It is an Ice Box Problem.</b><br> <br> <br> <br> <br> <br> <br> <br> <Br> <Br> <br> <br> <Br> <br> <br> <br> <br> <br> <Br> <br> <br>
