Given the following reversible reactions and Kc values: (I) Self-ionization of water:         H2O + H2O    H3O+ + OH-,   Kc = Kw = 1.0 x 10-14. (II) Ionization of a weak base:     NH3 + H2O    NH4+ + OH-,   Kc (= Kb) = 1.8 x 10-5. a) Determine the Kc­ for the reaction:                                     NH3 + H3O+  NH4+  +  H2O b)  Would you assess the Kc value as LARGE or small? Does your assessment make sense for this reaction, i.e. think about the species involved?

Question

Given the following reversible reactions and Kc values:

(I) Self-ionization of water:         H2O + H2O    H3O+ + OH-,   Kc = Kw = 1.0 x 10-14.

(II) Ionization of a weak base:     NH3 + H2O    NH4+ + OH-,   Kc (= Kb) = 1.8 x 10-5.

a) Determine the Kc­ for the reaction:

                                    NH3 + H3O+  NH4+  +  H2O

b) 

Would you assess the Kc value as LARGE or small? Does your assessment make sense for this reaction, i.e. think about the species involved?
