Consider: CO(g) + Cl2 (g) ⇌ COCl2 (g) Kc = 1.2×103 at 395 °C. If the equilibrium concentrations of Cl2 and COCl2 are the same at 395 °C, find the equilibrium concentration of CO in the reaction.

Answer : The equilibrium concentration of CO in the reaction is,

Explanation :

The given chemical reaction is:

The expression for equilibrium constant is:

As we are given:

Concentration of at equilibrium = Concentration of

So,

Therefore, the equilibrium concentration of CO in the reaction is,

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.
