factors which affect rate of reaction
o concentration
o pressure
o surface area
o temperature
o catalysts
How does concentration affect the rate of reaction
-A higher concentration means there are more reactant particles per unit volume,
-so a higher chance of the particles colliding,
-meaning there are more successful collisions so a higher rate of reaction
How does pressure affect the rate of reaction
-Increasing the pressure of a gas reaction can increase the rate of reaction,
-as it forces the gas particles to occupy a smaller volume,
-leading to more frequent collisions between the particles.
How does surface area affect the rate of reaction
-increasing the surface area of the reactants will increase the number of available sites for collision.
-This results in more successful collisions between reactant particles and a faster rate of reaction.
How does temperature affect the rate of reaction
-Temperature affects the rate of a reaction because increasing the temperature will increase the kinetic energy of the reactant particles.
-This results in more successful collisions between reactant particles and a faster rate of reaction.
How does a catalyst affect the rate of reaction
-A catalyst affects the rate of a reaction by lowering the activation energy required for the reaction to occur.
-This means that fewer collisions between reactant particles are needed to reach the energy threshold required for the reaction to occur, resulting in a faster rate of reaction.
