EP 5 Solubility/Equilbrium Problems from PPT

question 1.
Circle the letters of the terms that complete the sentence correctly. Stresses
that upset the equilibrium of a chemical system include changes in all except b .
a. concentration

c. pressure
d. temperature

question 2

When you add a product to a reversible chemical reaction, the reaction is always pushed in the direction of Reactants
When you remove a product, the reaction is pulled in the direction of products

question 3
What are the exponents in the equilibrium-constant expression?
A. Number of Moles

question 4
At a certain temperature, the equilibrium constant for this reaction is 11.1. Suppose that pure BrCl is placed in a 1-L container and allowed to come to equilibrium. Analysis then shows that the reaction mixture contains 4.00 moles of Cl2. How many moles of Br2 and BrCl are also present in the equilibrium mixture?
2BrCl(g) → Br2(g) + Cl2(g)
