Question

consider the following reversable reaction C(s)+O2(g) arrow thing, forgot what its called CO2(g). what is the equilibrium constant expression for the given system?

Answer 1

Equilibrium constant expression equals (pressure of co2)/(pressure of O2).you don’t include c in the expression because solids are never included and if pressure is not given and the volume is 1L use the number of moles given rather than the pressure.
