One mole of a monatomic ideal gas begins in a state with P=1.00 atm and T=300 K. It is expanded reversibly and adiabatically until the volume has doubled; then it is expanded irreversibly and isothermally into a vacuum until the volume has doubled again; and then it is heated reversibly at constant volume to 400 K. Finally, it is com pressed reversibly and isothermally until a final state with P=1.00 atm and T=400 K is reached. Calculate deltaSsys for this process. (Hint: There are two ways to solve this problem-an easy way and a hard way.)
Individuals that ingested MPTP, produced during the attempted synthesis of MPPP an analog of prodine, developed symptoms indicative of Parkinson's Disease. Something went wrong with the synthesis. Describe the synthesis of MPPP, and explain what w..
