All the Best! 1 / 10 pH of buffer depends mainly on concentration of acid concentration of salt ratio of salt to acid total volume 2 / 10 For a reaction with Q > K, the reaction will proceed forward backward at equilibrium irreversibly 3 / 10 For a reaction, Kc = 1.0 × 10³. The reaction is reactant favoured product favoured reversible impossible 4 / 10 The expression for Ka is [H⁺][A⁻]/[HA] [HA]/[H⁺][A⁻] [A⁻]/[HA] [H⁺]/[HA] 5 / 10 Strong acid has Ka value very small equal to 1 very large zero 6 / 10 Ionic equilibrium is mainly studied in gases solids plasma solutions 7 / 10 Increasing pressure will shift equilibrium forward if Δn = 0 Δn > 0 Δn < 0 catalyst present 8 / 10 If ΔG° is negative, K is less than 1 equal to 1 greater than 1 zero 9 / 10 If Δn < 0, increasing pressure shifts equilibrium forward backward no change irreversible 10 / 10 Buffer capacity increases with dilution higher concentration weak acid weak base Your score is 0% Restart quiz
