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. WebThere are five general properties that can affect the rate of a reaction: The concentration of the reactants. The more concentrated the faster the rate. Temperature. Usually reactions …

WebJul 23, 2024 · 1. 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. WebApr 12, 2024 · In a chemical reaction, the initial interval normally has the fastest rate (though this is not always the case), and the reaction rate generally changes smoothly over time. In chemical kinetics, we generally focus on one particular instantaneous rate, which is the …

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.
