Question:

a. Suggest a suitable method for following the progress of each of these reactions:

i. H₂O₂(aq) + 2I^–(aq) + 2H⁺(aq) → 2H₂O(l) + I₂(aq)

ii. HCOOCH₃(aq) + H₂O(l) → HCOOH(aq) + CH₃OH(aq)

iii. 2H₂O₂(aq) → 2H₂O(l) + O₂(g)

iv. BrO₃^–(aq) + 5Br^–(aq) + 6H⁺(aq) → 3Br₂(aq) + 3H₂O(l)

b. Why is it essential that the temperature is kept constant when measuring the progress of a reaction?
