Exercise 3 | Chemical Equilibrium

A reaction has a two steps mechanism with the following equilibrium constant:


K1 HO-HCO3-CO32-  and K2HCO3-HO-H2CO3 


Write the equilibrium constant expression and the chemical equation of the overall reaction.

Koverall = K1 x K2

KoverallHO-HCO3-CO32- x HCO3-HO-H2CO3 

Koverall = HCO3-2CO32-H2CO3 

 


2 HCO3(g)  CO32- (g) + H2CO(g)
