Rate of Reaction Lecture no 4 5070 Sir Tauqeer Asif

The rate of a chemical reaction is affected by several factors, including:
Concentration: The amount of reactants in a given area. A higher concentration means more molecules colliding, which increases the reaction rate.
Temperature: A measure of the kinetic energy of the molecules. Higher temperatures increase the average kinetic energy of the molecules, which increases the number of collisions per unit time.
Surface area: The total area of the reactants. Increasing the surface area increases the rate of reaction.
Pressure: Increasing the pressure on a gas reaction speeds up the reaction.
Catalyst: The presence of a catalyst increases the rate of reaction.
Reactant nature: The condition, reactivity, or solution type of the reactants affects the rate of reaction. For example, reactions in aqueous solutions happen quickly because the water molecules break down the bonds in the reactants.
State of subdivision: Whether the reactants are in one large lump or many small particles. Smaller particles have more surface area, which increases the reaction rate.
Radiation exposure: Exposure to radiation can affect the rate of a reaction
