1.	2 Pure nitrosyl chloride (NOCI) gas was heated to 240°C in a 1.0 L container. At equilibrium the total preswas 1.0 atm and the NOCI pressure was 0.64 atm. What would be the value of Kp?(1) 1.02 atm(2) 16.875 x 10 atm (3) 16 x 10 atm (4) of these
Answer» 2NOCl(g) <==> 2NO(g) + Cl2(g) 0.64 atm ...........0.24 atm..0.12 atm..... P(total) = 1.00 atm Kp = P(NO)² P(Cl2) / P(NOCl)² Kp = (0.24)² (0.12) / (0.64)² Kp = 0.017 ≃ 17 × 10⁻³ atm

2NOCl(g) <==> 2NO(g) + Cl2(g) 0.64 atm ...........0.24 atm..0.12 atm..... P(total) = 1.00 atm

Kp = P(NO)² P(Cl2) / P(NOCl)² Kp = (0.24)² (0.12) / (0.64)² Kp = 0.017 ≃ 17 × 10⁻³ atm
