How can a reaction rate be measured
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? Web12 de abr. de 2024 · The rate at which a battery is charged is usually measured in C. 50.Nominal voltage The approximate voltage at which a battery operates. It is lower than the battery's maximum voltage. 51.Maximum voltage The highest safe operating voltage of a battery. It is the highest power limit of a battery. An AoLithium battery can provide 12V.
