Un recipiente cerrado que contiene un gas ideal se reparte en dos volúmenes por un pistón móvil que no transmite calor (1 = 100 / , 2 = 200 /). La temperatura inicial en todo el recipiente es la misma (para los dos gases) y vale = 300 y la presión inicial también es la misma en todo el recipiente (para los dos gases) y vale 2 = 1,01 · 108 . Después, el gas de menor volumen se enfría hasta llegar a 1 = 273 , y el gas de mayor volumen se calienta hasta llegar a 2 = 373 . Suponiendo que la presión final de los dos gases es la misma, calculad esta presión.

Base your answer on the information below and on your knowledge of chemistry. nitrogen dioxide, no2, is a dark brown gas that is used to make nitric acid and to bleach flour. nitrogen dioxide has a boiling point of 294 k at 101.3 kpa. in a rigid cylinder with a movable piston, nitrogen dioxide can be in equilibrium with colorless dinitrogen tetroxide, n2o4. this equilibrium is represented by the equation below. 2no2(g) n2o4(g) + 58kj at standard pressure, compare the strength of intermolecular forces in no2(g) to the strength of intermolecular forces in n2(g).
