WebSome reactions are naturally faster than others. The number of reacting species, their physical state (the particles that form solids move much more slowly than those of gases or those in solution ), the complexity of the reaction and other factors can greatly influence the rate of a reaction. WebChemical reactions typically occur faster at higher temperatures. Food can spoil quickly when left on the kitchen counter. However, the lower temperature inside of a refrigerator slows that process so that the same food remains fresh for days. ... If temperature or reactant concentration is increased, the rate of a given reaction generally ...
WebPhysical state of reactants. Powders react faster than blocks - greater surface area and since the reaction occurs at the surface we get a faster rate. The presence (and concentration/physical form) of a catalyst (or inhibitor). A catalyst speeds up a reaction, an inhibitor slows it down. WebAbdullah Al Marzan, The greater the activation energy of a given reaction, the greater the sensitivity of the reaction rate to temperature changes. However, there is no clear relationship between ...
