Project #1482 - chemistry

1. What is equal in a state of equilibrium?

 

 

2. When equilibrium is reached, the concentration of reactants ___________

(increases, decreases, remains the same) and the concentration of products

___________ (increases, decreases, remains the same).

 

3. What does the value (the number) of Keq tell you?

 

 

 

4. Write a balanced equation for the synthesis of ammonia from its elements,

including the word "energy" as a product:

 

 

 

Write the Keq expression for the reaction above:

 

 

 

 

 

5. For the reaction, 2SO3 ! 2SO2 + O2, [SO3]=0.37M, [SO2]=0.25M,

[O2]=0.86M. Write the Keq equation, calculate Keq, and explain what this value

means.

 

 

 

 

 

6. For the equilibrium system PCl5 ! PCl3 + Cl2, Keq = 35. If the concentrations

of PCl5 and PCl3 are 0.025M and 0.68M respectively, what is the concentration

of the Cl2?

 

7. A reaction is in equilibrium when the concentration of the reactants and products are equal
