Detailed explanation-1: -Physical chemistry is the area that deals with the mechanism, rate, and energy transfer that occurs when matter undergoes a change.

Detailed explanation-2: -The answer is physical chemistry. Physical chemistry is the branch of chemistry that deals with the mechanism, the rate, and the energy transfer that occurs when matter undergoes a change.

Detailed explanation-3: -Recall that chemistry is the study of matter, its properties, the changes that matter undergoes and the energy associated with these changes.

Detailed explanation-4: -Chemistry is the study of the composition, structure, and properties of matter and the changes that matter undergoes. A chemical is any substance that has a definite composition or is used or produced in a chemical process.

Detailed explanation-5: -During a chemical reaction, bonds are broken, atoms are rearranged, and new bonds are formed. Breaking bonds and forming new bonds requires energy. These processes transform thermal or light energy into chemical energy, or vice versa.
