2NO + Cl2 ---------> 2NOCl
according to balanced reaction
assuming NO given = 12.0 g (if value is different answer will be different)
2 x 30 g NO reacts with 70.906 g Cl2
12 g NO reacts with 12 x 70.906 / 2 x 30 = 14.18 g Cl2.
but we have 17.8 g Cl2
so Cl2 is excess reagent .
excess Cl2 left over = 17.8 - 14.18 = 3.62 g

Nitrosyl chloride, NOCI, decomposes to form nitrogen monoxide gas and chlorine gas according to 2NOCI(g) = 2NO(g) + Cl2(g) Assuming that we start with no moles of NOCI(g) and no NO(g) or Cl2(g), derive an expression for K, in terms of the equilibrium value of the extent of reaction, Šeg, and the pressure p. Given that Ky = 2.00 x 10-4, calculate Šeg/no, when p = 0.080 bar. What is the new value of Šeg/no at equilibrium when p =...
