Le Chatelier's Principle
Le Chatelier's Principle states that if a dynamic equilibrium is disturbed, the system will adjust to minimize the disturbance. It's crucial for predicting how changes in concentration, pressure, or temperature affect chemical reactions. ScanSolve illustrates shifts in equilibrium with clear visuals and explanations.
How to Approach Le Chatelier's Principle
Identify the disturbance
Determine if the change involves concentration, pressure, or temperature (e.g., increased concentration of a reactant).
Apply Le Chatelier's Principle
Predict how the equilibrium will shift to counteract the disturbance (e.g., shift right to use up added reactant).
Analyze equilibrium position
Observe the new concentrations of reactants and products and how the reaction direction changes.
Frequently Asked Questions
What happens if pressure increases?+
Increasing pressure in a gaseous equilibrium will favor the side with fewer moles of gas.
Does temperature affect equilibrium?+
Yes, altering temperature shifts equilibrium depending on the reaction being exothermic or endothermic.
How does concentration change affect equilibrium?+
Adding more reactants or products shifts the equilibrium to the opposite side to re-establish balance.
