What is the equilibrium constant for HYDROLYSIS of Sodium Carbonate?

Na2CO3 + H2O --> NaHCO3 + NaOH ..... 1

NaHCO3 + H2O --> NaOH + H2O + CO2 .... 2

I need the Equilibrium Constants for both these reactions. At 25 deg C n 1 atm perhaps.

Those would be the Kb's for carbonate.

Kb1 = 2.08 * 10^-3
Kb2 = 2.38 * 10^-8

Clarify: Are you asking for the EXPRESSION or the actual numerical VALUE? Try looking online first. Google works wonders.
