2. Evaluation/Assessment:
Objective:
Today I will be able to:
Determine the concentrations of reactants and products initially and during equilibrium for a reaction by using an ICE table
Evaluation/Assessment:
Informal assessment: monitoring student questions as they complete the practice problems
Formal assessment: analyzing responses to the practice and exit ticket
Common Core Connection
Build strong content knowledge
Reason abstractly and quantitatively
Make sense of problems and persevere in solving them

9. Equilibrium Problems
The equilibrium constant can also be used to calculate equilibrium concentrations from initial concentrations
Use an ICE table!
To start with, we will use a generic equation
A(g) + B(g)  2 C(g)
[A] = .100 M and [B] = .100 M

10. A(g) + B(g)  2 C(g) A B 2 C Initial .100 M Change -x +2x Equilibrium
DISCLAIMER: THIS SLIDE IS JUST SHOWING YOU THE PROBLEM SET – UP NOT ENOUGH INFO TO SOLVE. SEE IN CLASS EXAMPLES.
A(g) + B(g)  2 C(g) A B
2 C
Initial
.100 M
Change -x
+2x
Equilibrium
.100 – x 2x
A and B are assigned –x values because they are being reacted, while C gets a +x because products are being formed. The 2x comes from the coefficient in front of the C

11. ICE Table Practice Problems
We will complete in class examples and then you will try on your own!
