thermo dynamics

Dear student,

Thermodynamics is the branch of science which studies the transformation of energy from one form to another.
Chemical thermodynamics looks at the energy transformations which occur as a result of chemical reactions.

The questions that chemical thermodynamics asks are:

• How much heat is evolved during a chemical reaction ("thermochemistry")?
• What determines the direction of spontaneous chemical change?
  For example, if you put a flame to a 2:1 mixture of H₂ and O₂ there is an almighty bang and the reaction proceeds spontaneously to products, i.e. without any further supply of external energy.
  Why does it not happen that water spontaneously goes to H₂ and O₂ when we put a lit taper to it under the same conditions?
