Ideal Gas Equation

CaCO3s⇌ CaOs+...

Question

$C a C O_{3} (s) ⇌ C a O (s) + C O_{2} (g), K = 10^{- 9}$ at $300 K$ . The value of $p_{c o_{2}}$ is $10^{- x}$ . $x$ is ____.

Solution

The equilibrium reaction is as given below:

$C a C O_{3} (s) ⇌ C a O (s) + C O_{2} (g)$ ,

The equilibrium constant is $K = 10^{- 9}$ at $300 K$ .

The expression for the equilibrium constant is $K = p_{c o_{2}} = 10^{- 9}$

Since calcium carbonate and carbon dioxide are solids, they do no appear in the equilibrium constant expression.

Hence, x is 9.
