The following reactions occur at 500 K. Arrange them in order of increasing tendency to proceed to completion (least → greatest tendency)

1. 2 NOCl ⇌ 2 NO + Cl2      Kp = 1.7 x 102
2. 2 SO3 ⇌ 2 SO2 + O2       Kp = 1.3 x 105
3. 2 NO2 ⇌ 2 NO + O2        Kp = 5.9 x 10–5

A. 2 < 3 < 1      B. 1 < 2 < 3     C. 3 < 1 < 2        D. 3 < 2 < 1        E. 2 < 1 < 3
