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 %.

Nitric oxide (no) can be formed from nitrogen, hydrogen and oxygen in two steps. in the first step, nitrogen and hydrogen react to form ammonia: n2(g) + 2 h_2(g) rightarrow 2 nh_3 (g) delta h = -92. kj in the second step, ammonia and oxygen react to form nitric oxide and water: 4 nh_3(g) + 5 o_2(g) rightarrow 4no(g) + 6 h_2o(g) delta h = -905. kj calculate the net change in enthalpy for the formation of one mole of nitric oxide from nitrogen, hydrogen and oxygen from these reactions. round your answer to the nearest .
