SO2 in a piston chamber kept in a constant-temperature bath at 25.0°C expands from 25.0 mL to 75.0 mL very, very slowly. Assume SO2 behaves as a van der Waals gas, and its van der Waals parameters are a-6.714 atm L/mol2 and b 0.05636 L/mol. If there is 0.00100 mole of ideal gas in the chamber, calculate ASy ASur and ASunv for the process.
