Question

what is true when a reaction has reached equilibrium?
the reaction has stopped
the reaction is faster in the reverse direction
the reaction rate is equal in both directions
the reaction is faster in the forward direction

Explanation:

Step1: Understand reaction equilibrium

Chemical equilibrium is a dynamic state.

Step2: Analyze each option

• Option A: Reaction doesn't stop, it's dynamic.
• Option B: At equilibrium, rates aren't faster in reverse.
• Option C: At equilibrium, \(v_{forward}=v_{reverse}\).
• Option D: At equilibrium, rates aren't faster in forward.

Answer:

C. The reaction rate is equal in both directions
