Question

Give example for first order reaction.

Answer 1

(i) Decomposition of dinitrogen pentoxide

N₂O₅ → (g) 2NO₂ (g) + 1/2 O₂ (g)

(ii) Decomposition of thionylchloride;

SO₂Cl₂(l) → SO₂ (g) + Cl₂ (g)

(iii) Decomposition of the H₂O₂ in aqueous solution;

H₂O₂ (aq) → H₂O (l) + 1/2 O₂ (g)

(iv) Isomerisation of cyclopropane to propene.
