Problem: Calculate the pressures of NO, Cl 2, and NOCl in an equilibrium mixture produced by the reaction of a starting mixture with 4.0 atm NO and 2.0 atm Cl2. (Hint: KP is small; assume the reverse reaction goes to completion then comes back to equilibrium.)2NO(g) + Cl2(g) ⇌ 2NOCl(g)             K P = 2.5 × 10-3
