WebFeb 27, 2024 · K = Q is balanced at equilibrium. It is that simple, yet textbooks almost pathologically put Q before K and then explain in words the direction of the reaction which is against the flow of the inequality. WebJul 10, 2024 · For a hypothetical weak acid H A ⇌ H + +A−. Ka = ( [H +][A−] H A) where [H +],[A−]&[H A] are molar concentrations of hydronium ion, conjugate base and weak acid at equilibrium. Example: Given a 0.10M weak acid that ionizes ~1.5%. [H +] = [A_] = 0.015(0.10)M = 0.0015M. [H A] ≈ 0.10M − 0.0015M ≈ 0.0985M. Ka = ( [H +][A−] [H A ...
