Which one of the following reactions would you expect to be fastest at room temperature and why?

Pb²⁺_(aq) + 2 Cl^-_(aq) → PbCl_{2 (s)}

Pb_(s) + Cl_{2 (g)} → PbCl_{2 (s)}

Consider the following reactions. Which do you predict will occur most rapidly at room conditions? Slowest?

C₂H_{6 (g)} + O_{2 (g)} → 2 CO_{2 (g)} + 3 H₂O_(g)

Fe_(s) + O_{2 (g)} → Fe₂O_{3 (s)}

H₂O_(l) + CO_{2 (g)} → H₂CO_{3 (g)}

2 Fe³⁺_(aq) + Sn²⁺_(aq) → 2 Fe²⁺_(aq) + Sn⁴⁺_(aq)
