Equilibrium position is the actual concentration of reactants and products at equilibrium. The concentrations of various substances at equilibrium depends on their initial concentration. Equilibrium constant being the ratio of concentrations of products to reactants remain unaltered.(T/F)

Answer

To determine whether the statement is true or false, we need to analyze the concepts of equilibrium position, equilibrium constant, and how they relate to the concentrations of reactants and products.

### Step-by-Step Solution:

1. **Understanding Equilibrium Position**:
- The equilibrium position refers to the actual concentrations of reactants and products when the reaction has reached equilibrium. This means that the rates of the forward and reverse reactions are equal, and the concentrations remain constant.

**Hint**: Remember that equilibrium position is about the specific concentrations of substances at equilibrium.

2. **Dependence on Initial Concentrations**:
- The concentrations of reactants and products at equilibrium can indeed depend on the initial concentrations of those reactants and products. Different starting amounts can lead to different equilibrium concentrations, although the ratio defined by the equilibrium constant remains the same.

**Hint**: Think about how changing the starting amounts of reactants can shift the equilibrium position.

3. **Equilibrium Constant (K)**:
- The equilibrium constant (K) is defined as the ratio of the concentrations of products to the concentrations of reactants, each raised to the power of their coefficients in the balanced equation. Importantly, K remains constant at a given temperature, regardless of the initial concentrations.

**Hint**: Recall that K is a fixed value for a reaction at a specific temperature, and it is derived from the concentrations at equilibrium.

4. **Conclusion**:
- The statement claims that "the concentrations of various substances at equilibrium depend on their initial concentration" is true. However, it also states that "the equilibrium constant remains unaltered," which is also true as long as the temperature does not change. Therefore, the overall statement is true.

**Final Answer**: True (T).
