Howdy,
i was wondering is anyone knows how a UV-visible spectroscopy works and how it differs to a double beam scanning spectrophotometer?
i know that UV visible spectroscopy needs a radiation source that is passed into a silt and then in a monochromator but how do u know how to poistion the monochromator to produce a red light to let's say to pass through a blue solution of CuSO4. And double beam scanning spectrophotometer uses motor what do those serve for?
and i have another question about equilibrium. if a 0.1 mole of N2O4 is introduced into 1L flask. the N2O4 dissociates into NO2 at equilibrium. 0.06 mole of N2O4 remain. Calculate the equilibrium constant for the reaction.
N2O4----->2NO2
Any help for any of the two questions would be awesome
Thanx :)
