Department of Chemistry Organizes a Scientific Course on the Effect of Temperature on Reaction Rate

The Department of Chemistry at the College of Education for Pure Sciences – University of Samarra organized a scientific course entitled “The Effect of Temperature on the Rate of Chemical Reactions in Nature.” The course was presented by Assistant Lecturer Rusul Rifaat Jameel, Assistant Lecturer Dua Abdulrazzaq, and Assistant Lecturer Reem Ibrahim Mahdi.

The presenters aimed to introduce the importance of the effect of temperature on the rate of reactions in nature, noting that an increase in temperature generally leads to an increase in the reaction rate, and that raising the temperature by 10 degrees Celsius results in a doubling of the reaction rate.

In this context, the lecturers explained that the Arrhenius equation shows that a chemical reaction cannot occur unless the reactants cross an energy barrier that separates them from the products. The reactants must overcome this barrier during their transformation into products through the formation of an intermediate compound, especially since the energy required to reach the peak of the energy barrier is higher.

At the conclusion of the course, several examples were presented illustrating the effect of temperature on the rate of reactions, including iron, mold, hot water and ice, snow, cooking food, and volcanoes.
