Achemical reaction occurring in a cylinder equipped with a moveable piston produces 0.621 mol of a gaseous product.

if the cylinder contained 0.120 mol of gas before the reaction and had an initial volume of 2.18 l, what was its volume after the reaction?

(assume constant pressure and temperature and that the initial amount of gas completely reacts.)

11.3 L

Explanation:

Initially, the cylinder had n₁ = 0.120 mol of gas in an initial volume V₁ = 2.18 L. At the end, it had n₂ = 0.621 mol in an unknown volume V₂. According to the Avogadro's law, in the same conditions of pressure and temperature, the volume is directly proportional to the number of moles.

> b takes place in the gas phase in an isothermal tubular reactor. the feed is one mole of a per one mole of c, an inert. the entering temperature and pressure are 427°c and 10 atm, respectively. the gas constant r = 0.08206 atm · l/mol · k.
