Describe the effect of changes in temperature, concentration, pressure, and surface area on ... WebThere are four main factors that can affect the reaction rate of a chemical reaction: Reactant concentration. Increasing the concentration of one or more reactants will often increase the rate of reaction. This occurs because a higher concentration of a reactant will lead to more collisions of that reactant in a specific time period.

WebThe yield and rate of a chemical reaction depend on conditions such as temperature and pressure. In industry, chemical engineers design processes that maximise the yield and the rate at which... WebCatalysts and activation energy. To increase the rate of a reaction you need to increase the number of successful collisions. One possible way of doing this is to provide an alternative way for the reaction to happen which has a lower activation energy. In other words, to move the activation energy on the graph like this:
