Rate of reaction 2 – Reaction rate and changing conditions
For a reaction to happen, reactant particles must collide with enough energy for the collision to be successful. The rate of reaction increases if there is an increase in temperature, concentration of reactants in solution or pressure of gaseous reactants. These changes can be explained in terms of the rate of successful collisions.
For a chemical reaction to occur, the reactant particles must collide with each other.
A collision with too little energy will not produce a reaction. The colliding particles must have enough energy for the collision to be successful or effective in producing a reaction.
The rate of a reaction depends on the rate of successful collisions between reactant particles. The more successful collisions there are, the faster the rate of reaction.
