Thermodynamics

V = 250 mL - 100 mL = 150 mL = 0.15 L = 2 atm W = - V = - (0.15 L) (2 atm) = - 0.3 Latm. = = 30.3975 J.

Step 1: Work done in isothermal expansion.
The work done during an isothermal expansion is given by: where: - , - . Convert from liters to cubic meters: Step 2: Substituting values.
Substitute the values into the work formula: Step 3: Converting to kJ.
The work done is , which is equivalent to . Thus, the correct answer is .
