Text Solution

AI Generated Solution

To solve the question, we need to understand the concept of chemical equilibrium and the relationship between the rates of forward and backward reactions. ### Step-by-Step Solution: 1. **Understanding Chemical Equilibrium**: - Chemical equilibrium occurs in a reversible reaction when the rates of the forward and backward reactions become equal. This means that the concentrations of reactants and products remain constant over time. 2. **Defining Forward and Backward Reactions**: ...
