At chemical equilibrium , the concentration of all reactants and products are equal

Answer

### Step-by-Step Solution

1. **Understanding Chemical Equilibrium**:
- Chemical equilibrium occurs when the rate of the forward reaction equals the rate of the backward reaction. At this point, the concentrations of reactants and products remain constant over time.

2. **Analyzing the Given Statement**:
- The statement claims that at chemical equilibrium, the concentrations of all reactants and products are equal.

3. **Identifying the Key Concept**:
- While the concentrations of reactants and products are constant at equilibrium, it is not necessary for these concentrations to be equal.

4. **Explaining with Graphs**:
- If we plot the concentration of reactants and products against time, the concentration of reactants will decrease and eventually stabilize, while the concentration of products will increase and also stabilize.
- At equilibrium, the concentrations are constant, but they can be different values.

5. **Conclusion**:
- Since the statement suggests that the concentrations must be equal, which is not a requirement for equilibrium, we conclude that the statement is **false**.

### Final Answer
The statement "At chemical equilibrium, the concentration of all reactants and products are equal" is **false**.
