Remember: Need to Write Down First Balanced Chemical Reaction and Equilibrium Constant Expression 
 
1. At 750degC, the following reaction reaches equilibrium in a 1-L container. 
<center>1 H2(g) + 1 <nowiki>CO</nowiki>2(g) <--> 1 H2O(s) + 1 <nowiki>CO</nowiki>(g)</center> 
At equilibrium, the 1-L flask contains 0.13moles hydrogen, 0.25moles carbon dioxide, and 0.57moles carbon monoxide. Calculate Keq for this reaction. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
2.For the reaction , 2 <nowiki>KClO</nowiki>3(s) <--> 2 <nowiki>KCl</nowiki>(s) + 3 O2(g) 
Keq = 2.3E-4. What is the equilibrium concentration of oxygen (O2)? What about the concentration of <nowiki>KClO</nowiki>3 and <nowiki>KCl</nowiki>?

3. For reaction 2 H2S2(g) <--> 2 H2(g) + 1 S2(g) 
a 0.50-L container initially has 4.00 moles of H2(g) and 2.50 moles of S2(g). At equilibrium, 75% of S2 has remained (left over) at equilibrium, what are the equilibrium concentration of all species and then calculated K (equilibrium constant)? 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
4. For the following, please write the equilibrium constant expression: 
<center> 1 <nowiki>Ca</nowiki>Cl2(s) --> 1 Ca2+ + 2 Cl1- 
 
 
 
 
From reading Pg533 (section 18.9), this K has a special name and symbol. What are they?
