Define a reversible reaction.
Think about whether the products can change back into what you started with.
What does dynamic equilibrium mean?
Consider what 'dynamic' suggests about movement!
What type of reactions can be reversible?
Think about how reactions behave in different thermal conditions.
True or False: The equilibrium constant always equals 1.
Consider how K might change for different reactions.
For the reaction 2CO(g) + O2(g) ⇌ 2CO2(g), what will happen to the equilibrium if you decrease the concentration of CO?
Think about how to restore the lost reactant.
Analyze how a temperature increase affects this reaction: N2(g) + 3H2(g) ⇌ 2NH3(g) ΔH = -92.4 kJ/mol.
Recall whether this reaction releases or absorbs heat.
