What is equilibrium in a reversible chemical reaction?
What is equilibrium in a reversible chemical reaction?
Forward rate equals backward rate
What happens to concentrations at equilibrium?
What happens to concentrations at equilibrium?
They remain constant over time
How do irreversible reactions proceed?
How do irreversible reactions proceed?
Only in the forward direction
What can reversible reactions do?
What can reversible reactions do?
Proceed in both directions
When is equilibrium established in reversible reactions?
When is equilibrium established in reversible reactions?
When both reaction rates are equal
Why must reversible reactions occur in a sealed container for equilibrium?
Why must reversible reactions occur in a sealed container for equilibrium?
So reactants/products cannot escape
Are reactant and product concentrations necessarily equal at equilibrium?
Are reactant and product concentrations necessarily equal at equilibrium?
No, they are not necessarily equal
What does the position of equilibrium indicate?
What does the position of equilibrium indicate?
Relative amounts of reactants/products
Can the position of equilibrium change?
Can the position of equilibrium change?
Yes, it shifts with condition changes
What is the net change in concentrations at equilibrium?
What is the net change in concentrations at equilibrium?
No net change occurs
