The following equation shows the reaction of hydrogen sulfate anion (HSO4-) with ammonia (NH3) to form sulfate (SO42-) and ammonium ions (NH4+):
HSO4-(aq) + NH3(aq) ⇌ SO42-(aq) + NH4+(aq)
If the value of Ka for HSO4- is 1.26 × 10-2, and the Kb value for NH3 is 1.8 × 10-5, determine whether the value of Kc will be greater than or lower than 1 for this reaction. Also, identify the direction which will be favored at equilibrium.
