Reaction 1 (decomposition of H₂O₂ by KI) is _____ than Reaction 2 (reduction of I₂ by NaS₂O₃) and therefore there will be no _____ present in the reaction flask until all S₂O₃^2- ions have reacted.

Reaksie 1 (ontbinding van H₂O₂ deur KI) is _____ as Reaksie 2 (reduksie van I₂ deur NaS₂O₃) en daarom sal geen _____ teenwoordig wees in die reaksiefles totdat al die S₂O₃^2- ione gereageer het nie.
