Le Chatelier’s Principle Lab Solutions and Explanations

Focus on identifying shifts in equilibrium when external factors such as temperature, pressure, or concentration change. This is the key to understanding how reactions respond to disturbances.

For temperature changes, remember that increasing heat typically favors the endothermic direction, while cooling favors the exothermic one. This concept is fundamental when analyzing reaction conditions.

When altering concentrations, observe how the system shifts to restore balance. Adding more reactant or removing product generally drives the reaction in the direction that produces more product.

Pressure changes affect systems with gases. If the number of moles of gas is unequal on both sides of the reaction, increasing pressure will shift the equilibrium towards the side with fewer gas molecules.
