← One mole of an ideal gas at 1.00 bar sits in a cylinder in a large water bath at 300 K. The external pressure on the piston is suddenly raised to 5.00 bar and held there, and the gas is squeezed until its pressure is 5.00 bar, ending at 300 K. Take R = 8.314 J K⁻¹ mol⁻¹ and 1 L bar = 100 J. What is the total entropy change of the gas and the water bath?At a certain temperature, Kc for 2 NO(g) + O₂(g) ⇌ 2 NO₂(g) is 1.6 × 10³, and Kc for 2 NO₂(g) ⇌ N₂O₄(g) is 4.0, both with concentrations in mol L⁻¹. What is the value of Kc at this temperature for NO(g) + 1/2 O₂(g) ⇌ 1/2 N₂O₄(g)? →
