A 0.10 M0.10\,\text{M} solution of the weak acid HA is prepared at 25∘C25^\circ\text{C}. The acid dissociation constant is Ka=1.0×10−5K_a=1.0\times10^{-5} for HA(aq)+H2O(l)⇌H3O+(aq)+A−(aq).\text{HA}(aq)+\text{H}_2\text{O}(l)\rightleftharpoons \text{H}_3\text{O}^+(aq)+\text{A}^-(aq). Which inequality is correct at equilibrium?
