Using thermodynamic data given for NO2 and N2O4, determine the fraction of N2O4 that will dissociate into two NO2 molecules if one mole of pure N2O4 is introduced to a 10 liter constant volume, constant temperature of 298K reactor. In addition determine the initial and final pressures within the reactor and the composition of the equilibrium vapor.
Complete and balance the following skeleton reaction and identify the oxidizing and reducing agents. include the states of all reactants and products in your balanced equation. don't have to include the states
Neat, aliphatic, primary amines show two absorptions between 3400 to 3330 cm-1 and 3330 to 3250 cm-1 due respectively to asymmetrical and symmetrical stretch. Stretch at 3300 cm-1. Why do tertiary amines not absorb in this region of the spectrum?
