Г. Е. Рудзитис Ф. Г. Фельдман - Школа Task 2 from the section covering paragraphs 18–20

For metals, oxidation (rusting) is a slow but steady destructive process. By applying protective coatings like paint or using inhibitors, we decelerate the reaction between iron and environmental oxygen/moisture, extending the lifespan of infrastructure like bridges and buildings. Рудзитис Ф

In daily life, we use refrigeration to decrease the kinetic energy of molecules, thereby slowing down the biochemical reactions and microbial growth that cause food to spoil. This "deceleration" allows for the long-term storage and global transport of perishables.

Essay: The Role of Reaction Rates in Industry and Daily Life

Conversely, many natural chemical reactions are destructive, and the goal of science is to slow them down.
