At equilibrium , the amount of each constituent of reaction mixture becomes …………

Explanation

To solve the question "At equilibrium, the amount of each constituent of the reaction mixture becomes …………", we can break it down into the following steps:

### Step-by-Step Solution:

1. **Understanding Equilibrium**:
- At equilibrium, a reversible reaction reaches a state where the rate of the forward reaction equals the rate of the reverse reaction. This means that the concentrations of the reactants and products remain constant over time.

2. **Concentration Changes**:
