(a) XeF_{2} is hydrolysed to release oxygen gas and causes the formation of elemental Xe and HF.

2XeF_{2}(s)+2H_{2}O (l)\rightarrow 2Xe(g)+4HF(aq)+O_{2}(g)

(b) SO_{2} acts as reducing agent andf hence when passed through the solution of Fe^{3+} salt, reduces it to Fe^{2+}.

SO_{2}+2Fe^{3+}+2H_{2}O\rightarrow 2Fe^{2+}+4H^{+}+SO_{4}^{2-}
