The equilibrium constant for the reaction, Ag 2 O(s) ⇌ 2Ag(s)   +   1 2 O 2 (g) is given by
Options
- AK = 2 A g 1 2 O 2 A g 2 O
- BK = [ A g ] 2 [ O 2 ] 1 2 [ A g 2 O ]
- CK = A g O 2 A g 2 O
- Dnone of the above
Correct answer
D. none of the above
Step-by-step solution
K = [ A g ] 2 [ O 2 ] 1 2 A g 2 O s By convention, [Solid] = 1 i.e., A g s = 1 and A g 2 O s = 1 So K = [ O 2 ] 1 2 .
