WebThe reaction rate of a chemical reaction is the amount of a reactant reacted or the amount of a product formed per unit time. Often, the amount can be expressed in terms of concentrations or some property that is proportional to concentration.

WebIn other words, reaction time rises with N, but once N gets large, reaction time no longer increases so much as when N was small. This relationship is called "Hick's Law." Sternberg (1969) maintained that in recognition experiments, as the number of items in the memory set increases, the reaction time rises proportionately (that is, proportional to N, not to log N). Web17 feb. 2016 · The final way we can affect the rate of a reaction is to use a catalyst. A catalyst is a chemical or biological agent that speeds up the rate of a reaction, without itself being used up in the process. It provides an alternative way for the reaction to occur, which has a lower activation energy. This means that less energy is required for two ...
