(a) Interpretation: The chirping rates should be determined at the temperature 25 C 0 and 35 C 0 . Concept introduction: The decomposition reaction can be determined when one compound is broken into two or more products.
(a) Interpretation: The chirping rates should be determined at the temperature 25 C 0 and 35 C 0 . Concept introduction: The decomposition reaction can be determined when one compound is broken into two or more products.
Solution Summary: The author explains that the decomposition reaction can be determined when one compound is broken into two or more products. The Arrhenius equation represents the relationship between the reaction rate and activation energy.
Definition Definition Transformation of a chemical species into another chemical species. A chemical reaction consists of breaking existing bonds and forming new ones by changing the position of electrons. These reactions are best explained using a chemical equation.

Interpretation Introduction
(a)
Interpretation:
The chirping rates should be determined at the temperature 25C0 and 35C0.
Concept introduction:
The decomposition reaction can be determined when one compound is broken into two or more products.
Interpretation Introduction
(b)
Interpretation:
The activation energy of the given reaction should be determined.
Concept introduction:
Activation energy is defined as the amount of energy required in the reaction to activate the atoms of molecules to undergo reaction and form a new product.
Interpretation Introduction
(c)
Interpretation:
The percentage increase in rate for rise of 10C0 temperature should be determined.
Concept introduction:
The rate of reaction represents the speed of the chemical reaction process.
