Three treatments of different starting materials are listed. Which statement explains the treatments? Substance 1 was activated by a decrease in temperature, Substance 2 was activated by the change in concentration, and Substance 3 decreased the surface area. Substance 1 was activated by a decrease in temperature, Substance 2 was activated by the change in pressure, and Substance 3 increased the surface area. Substance 1 was activated by the heat and inactivated by ice, Substance 2 was activated by the change in pressure, and Substance 3 decreased the surface area. Substance 1 was activated by the heat and inactivated by ice, Substance 2 was activated by the change in concentration, and Substance 3 increased the surface area.

Substance 1 was activated by the heat and inactivated by ice, Substance 2 was activated by the change in concentration, and Substance 3 increased the surface area.

The treatment is explained by temperature in the first substance, concentration in substance 2, and surface area in substance 3. Thus, option D is accurate.

What are the factors of reaction rate?

The rate of the reactions is concerned with the temperature concentration, surface area, etc. Their involvement increases and decreases the reaction rate of the substance present in the reaction mixture.

An increase in temperature by heat increases rate, and ice decreases temperature hence decreasing rate. The second substance starts with an increase in the concentration and the third by increasing surface area.

Therefore, option D. is the treatment for the substances.
