What is c K for the following equilibrium when equilibrium concentration of each substance is [SO ] 0.60 M, [O ] 0.82 M and [SO ] 1.90 M ? (VMMC 2010) 2SO (g) O (g) 2SO (g)

Here, 2 2 3 2 3 C 2 2 2 3 2 2 2 C 2 C 2SO (g) O (g) 2SO (g) SO K = O SO SO 1.90M SO 0.60M O 0.82M (1.9) K (0.82)(0.6) K 12.229 Hence, option (a) is the correct answer.
