(a) Hydrogen peroxide (HOOH) has a pKa of 11.6, making it roughly 10,000 times as strong an acid as water(pKa = 15.7). Explain why H2O2 is a stronger acid than H2O.(b) In contrast to part (a), peroxyacetic acid (pKa = 8.2) is a much weaker acid than acetic acid (pKa = 4.74). Explainwhy peroxyacetic acid is a weaker acid than acetic acid.(c) Peroxyacetic acid (bp = 105 °C) has a lower boiling point than acetic acid (bp = 118 °C), even though peroxyaceticacid has a higher molecular weight. Explain why peroxyacetic acid is more volatile than acetic acid
