What is equilibrium in a chemical reaction?
Think about what happens when there are no changes in concentration.
What does a high value of Kc indicate?
Recall the scale related to Kc values.
If Kc = 2.1 × 10^5 for the reaction, what does that imply?
Consider the implications of reaction extent.
True or False: Increasing the concentration of reactants will shift equilibrium to the left.
Refer to Le Chatelier’s principle.
Calculate the concentrations of reactants and products at equilibrium given an initial concentration and the equilibrium constant.
Use the stoichiometry of the balanced equation to assist in your calculations.
Given a shift in equilibrium due to temperature change, describe the expected changes to K.
Reference how exothermic reactions behave under temperature changes.
