Question

consider the following reversible reaction. C(s) + O2(g) CO2 (g) what is the equilibrium constant expression for the given system​

Answer 1

B.)

Step-by-step explanation:

Answer 2

Equilibrium constant expression is the ratio of product of concentration of products and product of concentration of reactants.

Here K= [CO2]/[O2]

Note: Solids won't contribute to equilibrium constant expression since their activity is always one.
