  1. Enthalpies of Reaction3rd year Chemistry Ms. Tamala September 20, 2012

  2. Enthalpy of Reaction • The beat of the reaction • The charge that accompanies reaction • Thermo chemical equations as associated enthalpies • ∆Hrxn,where “rxn” is commonly used abbreviation for “reaction” • Enthalpy diagram change of enthalpy

  3. Guidelines using Thermo chemical equations and Enthalpy Diagrams: b c A • (a) candle is held near a balloon filled with Hydrogen • (b) The H2 ignites reacting with CO2 to form H2O. The resultant explosion produces the balloon gives heat to its surroundings • (c) the enthalpy diagram

  4. Effects of Enthalpy Change • Explosion is led to the discontinuation of hydrogen as buoyant gas • Modern-day blimps are filled with Helium, which is not as buoyant as Hydrogen, but is not flammable

  5. Enthalpies of Reaction is associated with Chemical Reactions which is more buoyant and dangerous
