For the following questions, consider the isothermal compression of a 2.0 mol sample of ideal gas from an initial volume of 4.7 L to a final volume of 2.8 L. The compression takes place at 298 K. a) What is the sign of work for this process? Provide an explanation to support your answer that includes what is occurring in the gas sample on the molecular level. b) Calculate the work done if the gas expands against a constant external pressure to 15 atm. Your answer should be reported in units of energy (J or kJ). c) Would the work when compressing the gas reversibly be less than or greater than the irreversible work computed in part b? Calculate the value or explain your choice.
