    1) is definitely out as it requires the OH group to act as an acid and release a H+ . which is not possible in the presence of H2SO4

    First question was explained in #17975 For the 2nd question, moles of ethanol = 2.3/46 = 0.05 mol moles of ethanoic acid expected = 0.05 mol mass of ethanoic acid expected = 3 g actual mass obtained = 60% x 3 g = 1.8 g

    yes, it is used to provide an acidic environment, but it is not the oxidizing agent, the KMnO4 is the oxidising agent

    Do you mean that the answer was B and not D?

    Hold on, the oxidizing agent should be the KMnO4 and not sulfuric acid

    If the question was phrased such that the temperatures (energy) of the operating system was adjusted, then a catalyst is relevant. Here, they are talking about pressure conditions.

    Yes, possible to crack with enough energy. But the issue is that they do not yield products of much commercial value in most cases

    H2SO4 + aq => H^+ + H2SO4^- Due to full dissociation at the first stage, from 1 mole of H2SO4, we will get 1 mole of H+ and 1 mole of HSO4^- HSO4^-(aq) <=> H^+(aq) + SO4^2- Due to partial dissociation at the second stage, from 1 mole of HSO4^-, we will get << 1 mole of H+ and << 1 mole of...

    Chemistry MCQ thread...

    Yes, that is correct. The Kc of the forward reaction is the reciprocal of the backward reaction.
