which factor can decrease the rate of a chemical reaction?
1 A decrease in particle size causes an increase in the solid's total surface area.  Raising the reaction temperature by 10 Â°C can double or triple the reaction rate. This is due to an increase in the number of particles that have the minimum energy required. The reaction rate decreases with a decrease in temperature.
1 This is due to an increase in the number of particles that have the minimum energy required. The reaction rate decreases with a decrease in temperature.  Catalysts can lower the activation energy and increase the reaction rate without being consumed in the reaction.
