Question

For the following reactions, occurring at 500 K, arrange them in order of increasing tendency to proceed to completion (least $\to$ greatest tendency)

$1 .$ $2 N O C l ⇌ 2 N O + C l_{2}; K_{p} = 1.7 \times 1 0^{- 2}$

$2 .$ $2 S O_{3} ⇌ 2 S O_{2} + O_{2}; K_{p} = 1.3 \times 1 0^{- 5}$

$3 .$ $2 N O_{2} ⇌ 2 N O + O_{2}; K_{p} = 5.9 \times 1 0^{- 5}$

TestHub · Accepted Answer

The greater the magnitude of equilibrium constant, the more the tendency of the reaction to proceed to completion. Hence the correct order of increasing tendency to proceed to completion (least → greatest tendency) 2 < 3 < 1.
