Question

V 35 Solid phosphorus trichloride, PCl3 (molar mass = 137 332 g/mol) is a commercially important component of pesticides and gasoline additives andis made by the reaction of phosphorus (as P4 molar mass = 123.985 g/mol) and chlorine gas (molar mass = 70.905 g/mol). P4(s) + 6 C12(g) – 4 PC13(s) What mass (g) of PCls will be formed if 125 g of Pa is placed in a 55.0 L tank that contains chlorine gas at 32°C and 2.10 atm? 16) V hl@ VOO@@WP XOCIETALL

Answer 1

Puls) + 6 Cl₂(g) 4 Pelz (3) From the equation we see that a 4 more of pet with I mole Py the neaction of will produce 6 mole legs. T= 32+273 = 305k P- 21.0 atm. V= 55.0L. n = PV=MRT. PV 21.0 X 55.0 0.082 305 46.18 a) n = 464.84 more of C2 (9) RT 125 g of Puls) = 125 = 1.00818 more P415) 123.985 So as Puis smauer in amount , it will be the limiting agent so from 1.00818 more Pulss we will get (1.00 8 18 x 4) - 4.0327 more Pelz (5) Molar mass of Pez(3) = 137, 33 . 4.0327 more pelz(5) = 5 53.8 pelz(s) will be formed.
