JEE Main Chemistry question
The formation of phosgene is represented as CO+Cl₂⇌COCl₂. The reaction is carried out in a 500 mL flask. At equilibrium 0.3 mole of phosgene, 0.1 mole of CO and 0.1 mole of Cl₂ are present. The equilibrium constant of the reaction is:
Answer: (B)
Solution
[COCl₂]=0.6,[CO]=[Cl₂]=0.2. Kc=0.6/(0.2×0.2)=15.
