Answer:
B. A reaction at equilibrium will respond to balance a change.
Explanation:
The Le Chatelier's principle states that a reaction will respond to balance a change. This is true for a reaction in chemical equilibrium.
Le Chatelier's principle sates that "if any conditions of a system in equilibrium is changed, the system will adjust itself in order to annul the effect of the change".
- It explains the effect of applying stress on any system in equilibrium.
- The changing conditions are usually concentration, temperature and pressure.
- If the stress due to any of them is applied to a system in equilibrium, the equilibrium will respond in the directions which counteracts the effect of the stress.
