which of the following gives the relative size of Ka and pH of a 0.10 M solution of HEX3(aq)?

HEX3(aq) + H2O(l) ⇌ H3O+(aq) + EX3(aq)

∆Go = +47 kJ/molrxn


The reaction between the acid HEX3(aq) and water is shown above. Based on the chemical equation and the value of ∆Go given above, which of the following gives the relative size of Ka and pH of a 0.10 M solution of HEX3(aq)?

  1. Ka = 1 and pH < 1


  1. Ka << 1 and pH = 1


  1. Ka > 1 and pH > 1


  1. Ka << 1 and pH > 1
