Homework Help: Rates of reaction

  1. Apr 23, 2006 #1
    explain why the reaction lumps of calcium carbonate is much slower with 0.1 M ethanoic acid than with 0.1 M hydrochloric acid at the same temperature.

    any ideas?

    HINT: Think about what actual reacts with the calcium carbonate (think ions)
    BIG HINT: One is a weak acid and the other is a strong acid.

    Consider how carbonate reacts with each respective acid in the aqueous solutions, the equilibrium pH of each respective acid solution, Ksp equation, common ion effect.
