Snapshots
Details
Snapshot 1: system at the equilibrium: the initial concentration fulfils the equilibrium constant equation, so there is no change
Snapshot 2: Le Chatelier's principle: raising the temperature in the equilibrium state causes a shift of an endothermic reaction toward the product side
Snapshot 3: lowering the temperature of an exothermic reaction increases the value of and consequently shifts the equilibrium toward the product side
Snapshot 4: raising the temperature of an endothermic reaction increases the value of and consequently shifts the equilibrium toward the product side
