A vessel contains 1 mol of gas A and 2 mol of gas B at 2 bar and 25 °C. The gas mixture is compressed such that the final pressure becomes 3 bar without any change in temperature. Considering ideal gas behaviour, the change in Gibbs free energy (in kJ) during the compression is closest to [Given: Gas constant, R=8.314 J mol−1 K−1R = 8.314 \text{ J mol}^{-1} \text{ K}^{-1}R=8.314 J mol−1 K−1]
