1 / 10
ICE Table / RICE Table
Not Started

A setup listing initial, change, and equilibrium amounts to solve for unknown equilibrium concentrations.

7.7.A7.7.A.1
Initial, Change, Equilibrium Rows
Not Started

Initial lists starting amounts, change uses stoichiometric x values, and equilibrium combines initial plus change.

7.7.A7.7.A.1
Stoichiometric X Relationships In ICE Tables
Not Started

Species change by coefficient multiples of x, with reactants negative and products positive.

7.7.A7.7.A.1
Reaction Quotient Compared With Equilibrium Constant
Not Started

If Q < K products form, if Q > K reactants form, and if Q = K equilibrium exists.

7.7.A7.7.A.2
Dynamic Equilibrium
Not Started

Forward and reverse reactions occur at equal rates, so concentrations remain constant.

7.7.A7.7.A.2
Equilibrium Constant Expression With ICE Values
Not Started

Substitute equilibrium concentrations or partial pressures from the table into the K expression.

7.7.A7.7.A.1
Solving For X In Equilibrium Problems
Not Started

Use the K equation after substitution, then solve algebraically for the unknown change variable.

7.7.A7.7.A.1
Equilibrium Concentrations Vs Partial Pressures
Not Started

Use molar concentrations for Kc problems and partial pressures for Kp problems.

7.7.A7.7.A.1
Given And Zero Initial Values In ICE Tables
Not Started

Use provided starting amounts, and assign zero to species not initially present unless stated otherwise.

7.7.A7.7.A.1
5% Approximation In Equilibrium Problems
Not Started

Treat a ± x term as constant when x causes less than 5% error.
