How can a reaction rate be measured
WebThe average rate of reaction can be calculated by considering how the mass changes over a fixed period of time. This will give a rate measured in grams per second (g s-1) using … Webreaction rate the speed at which a chemical reaction happens. Measures the decrease in concentration of a reactant, or the increase of a product, with time. Four factors that affect reaction rate 1. Surface area 2. Reactant concentration 3. Reactant temperature 4. Presence of a catalyst How does surface area affect reaction rate?
