Basic
This branch of chemistry that studies the energy changes during chemical reactions in the form of heat.
What is Thermochemistry?
The amount of energy needed to break one molecule of a particular bond.
What is Bond Energy?
“thermes” meaning heat, and “dynamikos,” meaning powerful.
What is Thermodynamics?
Thermochemistry primarily focuses on this form of energy.
What is heat?
The unit used in determining Bond Energies.
What is Kj/mol Kcal/mol?
The energy transferred between two substances or systems due to a difference in temperature.
What is Heat?
It states that energy cannot be created or destroyed in chemical reactions is known as this.
What is the first law of thermodynamics?
Higher bond energy means a stronger bond, which requires more energy to break.
Total kinetic energy of the molecules in the system, it is proportional to the thermal energy of an object
What is Temperature?
A chemical reaction that releases energy in the form of heat.
What is an exothermic reaction?
This describes the amount of energy stored in a bond between atoms in a molecule.
What is Bond Enthalpy?
The Change in internal energy of the system.
Internal Energy (Delta U)
The energy absorbed or released by a system during a reaction is known as this.
The formula in getting the Bond Enthalpy of a molecule?
What is H = (Energy of Bonds Formed) - (Energy of Bonds Broken)?
It is used in solving for the change in internal energy of a system?
What is ΔU=Q−W?
