A sample of gaseous arsine (AsH3) in a 476 mL
flask at 327 Torr and 231 K, is heated to
445 K, at which temperature arsine decomposes to solid arsenic and hydrogen gas. The flask is then cooled to 281 K, at which temperature the pressure in the flask is 485 Torr.
What percentage of arsine molecules have decomposed?
Answer in units of %.
