write the equilibrium-constant expression and calculate the value of the equilibrium constant for each of the following reactions at 298 K.

Question

(a) NaHCO3(s)<--> NaOH(s) + CO2(g)
Answer: Keq = PCO2

(b)Value of the Equilibrium Constant:

Please help me find B

Answer 1

You don't have enough information posted.

Answer 2

........ deltaHf(KJ/mol)...... d.Gf(KJ/mol)..... d.S(J/mol-K)

NaHCO3(s) -947.7...... -851.8 ......... 102.1
NaOH(s).. -425.6 ...... -379.5 ........ 64.46
CO2(g) .. -393.5 ...... -394.4 ........ 213.6

Hope that helps

Answer 3

dGo= -RTlnK
You should be able to get dGo from
dGorxn = (n*dGof products) - (n*dGof reactants)
