What is the effect of the temperature of reactants on the production rate of a chemical reaction ?
There are five factors that control the rate of a chemical reaction including the nature of the reactants, their concentration, catalysts, surface area, and temperature. A chemical reaction happens when the molecules of two different reactants collide with enough energy to break apart. Temperature effects the number and strength of the molecular collisions. The warmer the reactants the more the molecules move causing more frequent and stronger collisions, thus the warmer the reactants, the quicker the production rate of the reaction. Again, while temperature can increase the rate of production, the other factors can influence how much of an increase in production a warmer temperature is able to cause.
The hotter(higher) the temperature the faster the reaction, because the molecules move faster. The colder(lower) the temperature the slower the temperature, due to the molecule movement being slower.
Effect of Temperature:
When gases or liquids are heated the particles gain kinetic energy and move faster. The increased speed increases the (frequency) of collision between reactant molecules and the rate increases. This effect is observed for both exothermic and endothermic reactions. A general approximate rule for the effect of temperature on reaction rates is that the reaction rate for most of the chemical reactions becomes almost double, for every 10 0C rise in temperature.
