WebA student measured the rate of a reaction at two different temperatures: 40∘C and 50∘C. They observed that the rate of reaction roughly doubled. What explains this observation? A raising the temperature by 10∘C doubles the average velocity of the molecules B raising the temperature by 10∘C doubles the average kinetic energy of each molecule C 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?
