Equilibrium Quiz
ICE Boxes
 Objective:
 Today I will be able to:
 Apply Le Chatelier’s principle and writing equilibrium expressions to a
quiz
 Determine the concentrations of reactants and products intitially and
during equilibrium for a reaction by using an ICE table
 Evaluation/Assessment:
 Informal assessment: monitoring student questions as they
complete the quiz and the practice problems
 Formal assessment: analyzing responses to the quiz, practice
and exit ticket
 Common Core Connection


Warm - Up
• Take everything off of your desk for
the quiz.
• Place a sticky note on your phone and
place it in Mr. Klotz’s bin
– Make sure your phone is on silent

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
DISCLAIMER: THIS SLIDE IS JUST SHOWING YOU THE PROBLEM SET –
UP. THIS IS NOT ENOUGH INFO TO SOLVE. SEE IN CLASS EXAMPLES.

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
