WebFast → NO 2 + CO 2 Rate = K [NO 2]2 Factors affecting Rate of reaction: 1. Nature of Reactant: IA elements react more faster with water than IIA elements Neutralization / ionic reactions/double decomposition reactions are very fast, whereas redox reactions are slow 2. Concentration of Reaction: Webfast, compared with many reactions which undergo, instead, a breaking of chemical bonds and a fonning of new ones. Accordingly, the study ofa large body of fast electron transfer reactions became accessible with the introduction of this instrumentation. One example of the latter was the stopped-flow apparatus,
