As temperatures rise the rate of reaction increases and vice versa, because as temperatures rise and the temperature increases, the movement of the molecules increase as the molecules collide with greater force which means that the reaction happens faster. Normally as the temperature increases to 100C and the rate of reaction increases by between 2 and four times.

If the temperature of the reaction is raised to t0C, the rate of reaction will increase by 10/10 (where A is the coefficient of temperature and how many times that the rate increases each time the temperature increases up to 100C).

When the concentration of reactants rises as does the rate of reaction also increases (this can be seen clearly in the expression (2) because , as the concentration of reactants rises the collisions between components of reactants and the effectiveness of collisions) rise.
