Thermochemistry Introduction All chemical reactions and phase changes involve energy. One form of energy is heat: when a change in the energy of a system results in a temperature difference, we say that energy has been transferred as heat. An equation that expresses heat in the internationally accepted energy unit of Joules (J) is

Thermochemistry 1. 11.Given: N 2(g) + 3 H (g) Î 2 NH 3(g) + 92.5 KJ, what is ∆Hf° for NH (g)? 2. Given: CaCO3(s) Î CaO(s) + CO2(g) ∆H = 175 kJ Ca(OH)2(s) Î H2O(l) + CaO(s) ∆H = 67 kJ
All forms of energy can be interconverted. Three things can change the energy of an object: the transfer of heat, work performed on or by an object, or some combination of heat and work. Thermochemistry is a branch of chemistry that qualitatively and quantitatively describes the energy changes that occur during chemical reactions.
Thermochemistry is the study of energy changes that occur during chemical reactions and changes in state When studying energy, a system is defined - the part of the universe on which you focus your attention Surroundings are the part of the universe outside of the system
Thermochemistry Common Misconceptions • Power and energy are different. Power refers to the amount of energy that is consumed in a period of time, and since work is a form of energy in transit, we can also say that power is the amount of work performed per unit time. • Heat and temperature are different.
