WebNov 11, 2013 · Because, generally, but not always, reactions with high activation energies tend to be slow, and "people" tend to be honest about such things. For specific cases, it is probably possible to find a reaction with a higher activation energy that proceeds faster. WebTherefore, the rate of reaction is fastest in the reaction with iron filings. The results from the experiment are not surprising. The iron filings have a much greater surface area than the iron ribbon. Usually, the greater the surface area, the faster the rate of reaction. dalitso project arbroath

It is correct to say: "If nothing else changes, an increase in temperature will increase the rate of an elementary step of a chemical reaction". All kinds of things could go wrong. If the temperature is so high that your reaction vessel melts, spilling a liquid reactant and removing it from a solid reactant, the rate will not increase.
