Equilibrium - Calculating Concentrations at Equilbrium
K = [products] ÷ [reactants]
This page is an exercise in calculating the concentrations of reagents (reactants or products) at equilibrium. When you press "New Problem" a balanced equation and a set of some initial and equilibrium concentrations will be displayed. Use the information provided to determine the value of the missing concentration.
To begin, click "New Problem" and a question will appear in the box below the button.
IMPORTANT: Put the correct value into the answer cell and click "Check Answer."
The results on the problem and a running total will appear in the second table.
Pressing "Show Answer" will display the correct value and you will no longer be able to enter an answer for that question. At this time, you'll only get the value, not a detailed explanation.
