![### Ideal Gas Proof for Thermodynamics
**Problem B1:**
Prove that for a 1-component ideal gas the following relationship holds:
\[ G(T, P_2, n) = G(T, P_1, n) + nRT \ln \left( \frac{P_2}{P_1} \right) \]
**Explanation:**
In this formula:
- \( G \) represents the Gibbs free energy,
- \( T \) is the temperature,
- \( P_1 \) and \( P_2 \) are the initial and final pressures, respectively,
- \( n \) is the number of moles,
- \( R \) is the universal gas constant,
- \( \ln \) denotes the natural logarithm.
To solve this problem, you'll need to apply concepts from thermodynamics, especially how Gibbs free energy changes with pressure for an ideal gas. The derivation involves integrating the fundamental equation relating Gibbs free energy and pressure at constant temperature.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F37df213a-2c14-4822-a979-37f159717cfc%2Ff94ab176-6401-4ec5-86c6-d98298024d82%2F65kxpm_processed.png&w=3840&q=75)
