if gases are involved in the reaction.
If the reaction occurs in the gas phase
If the reaction occurs in the gas phase
If the pressure increase the number of intermolecular collisions increase and so the reaction rate. This is valid for gases.
If the pressure increase the number of intermolecular collisions increase and so the reaction rate. This is valid for gases.
The frequency of collisions is changed.
Doubles it
The frequency of collisions is changed.
The concentration of reactants is changed.
Increasing the temperature the reaction rate increase.
Examples: temperature, pressure, concentrations, stirring, particles dimension, catalysts etc.
There are several factors that affect the rate of reaction: -The surface area available. -Temperature -Availability of catalyst. -Concentration, if a/the reactant(s) is/are solutions. -Pressure, if a/the reactants(s) is/are gases. -Reactivity of reactants. -Activation energy of the reaction.
Increasing the concentration of the reactants increases the rate of the reaction.
