Question

Write an equilibrium constant expression for the following heterogeneous equilibria: 2NaHCO3(s) Na2CO3(s)+H2O(g)+CO2(g)

Answer 1

2NaHCO3(s) ----> Na2CO3(s)+H2O(g)+CO2(g)

\[Kc= \frac{ product }{reactant }\]

Answer 2

coefficients in the equation will be powers in this formula

Answer 3

so it'll be like this
\[Kc= \frac{ [Na_2CO_3]\times [H_2O]\times [CO_2] }{ [NaHCO_3]^2 }\]

Answer 4

hope it helps :)
