**Chemical Equilibrium: Conversion and Concentration Analysis**

In this lesson, we will explore how to calculate the equilibrium conversion and concentration for a chemical reaction. The focus will be on the following reversible reaction:

\[ 2A \rightleftharpoons B \]

This reaction is performed in a flow reactor, where pure substance A is introduced at a concentration of 4.0 mol/dm³. The equilibrium conversion of substance A is observed to be 60%. Based on this information, we will address the following questions:

1. **Equilibrium Constant for Gas Phase Reaction:**
   - Determine the equilibrium constant, \( K_c \), assuming the reaction occurs entirely in the gas phase.

2. **Equilibrium Constant for Liquid Phase Reaction:**
   - Calculate \( K_c \) for the scenario where the reaction takes place in a liquid phase. 

By understanding and solving these questions, you'll gain insights into how equilibrium concepts adapt based on the physical state of the reactants and products.
