Final answer:
When a chemical system at equilibrium is disturbed, it reacts by following Le Chatelier's Principle, responding in a way to counteract the disturbance and restore equilibrium.
Step-by-step explanation:
The question relates to how a system at chemical equilibrium responds to a disturbance. If the system is disturbed, one rate temporarily increases until a new equilibrium state is reached. This is a description of Le Chatelier's Principle. According to this principle, when a chemical system that is at equilibrium is disturbed by a stress, such as changes in temperature, concentration, pressure, or volume, the system will respond by shifting in a direction that counteracts the disturbance and re-establishes equilibrium.
