... The most negative  can be is thus –1/2 mol. (Note, too, that nH2 = 11/2 mol and nN2 = 5/2 mol when  = –1/2 mol.) If N2 and H2 react to form more NH3, then  will be positive. The maximum  will be determined by the limiting reagent: does one deplete H2 first, or N2? Since every mole of N2 that rea ...

Ultraviolet–visible spectroscopy



Ultraviolet–visible spectroscopy or ultraviolet-visible spectrophotometry (UV-Vis or UV/Vis) refers to absorption spectroscopy or reflectance spectroscopy in the ultraviolet-visible spectral region. This means it uses light in the visible and adjacent (near-UV and near-infrared [NIR]) ranges. The absorption or reflectance in the visible range directly affects the perceived color of the chemicals involved. In this region of the electromagnetic spectrum, molecules undergo electronic transitions. This technique is complementary to fluorescence spectroscopy, in that fluorescence deals with transitions from the excited state to the ground state, while absorption measures transitions from the ground state to the excited state.
