23 sty 2013 · The average rate is calculated over an interval of time, while the instantaneous rate is the actual rate at a given time. Several factors affect the rate of reaction, including the total surface area and concentration of reactants, temperature, use of catalysts, and pressure for gaseous reactants.
10 gru 2016 · The document discusses the rate of chemical reactions and factors that affect it. It defines the rate of reaction as the speed at which a chemical reaction occurs. Some reactions are very fast, like wood combustion or nuclear explosions, while others are slow, such as iron rusting.
12.3 Conditions that Effect Reaction Rates. • Increasing the concentration (or surface area) of reactants or the reaction temperature increases reaction rate by increasing the number of effective collisions. 14.
Section 17.1 Reaction Rates and Equilibrium 1.Understand how particles in a mixture react with each other and the main factors that speed up or slow down.
Factors Influencing the Reaction Rate: Reactivity of the Substances: Iron (Fe): Iron is a moderately reactive metal, meaning it readily participates in chemical reactions, particularly oxidation. Oxygen (O₂): Oxygen is a highly reactive non-metal, making it a strong oxidizing agent that readily reacts with metals. Surface Area: The larger the surface area of the iron, the faster the reaction.
Factors that affect reaction rates include temperature, surface area, concentration, and presence of catalysts. Higher temperatures increase particle energy and collision rate. Smaller particles and higher concentrations increase collision opportunities.
