Hydrogenation reactions are used to add hydrogen across double bonds in hydrocarbons and other organic compounds.
Use average bond energies to calculate DELTA Hrxn for the following hydrogenation reaction:
H2C==CH2(g) + H2(g)-->H3C--CH3(g)
2)Use standard enthalpies of formation to calculate DELTA Hrxn for the following reaction.
CH4(g)+2O(g)--->CO2(g)+2H2O(g)
Give some values of pressure and temperature at which you are sure that the substance called zinc exists in an equilibrium state as a) solid and b) vapor
the Standard Gibbs energy change associated with this oxidation reaction is ca. 0. kJ/g.
