Calculate the vibrational partition function of CS2 at 500K given the wavelength 558 cm-1 (symmetric stretch), 397 cm-1 (bend; two modes), and 2097 cm-1 (asymmetric stretch)
When equilibrium is reached at 700C, the total pressure of the system is found to be 4.00 atm. If the equilibrium constant Kp for this reaction is equal to 1.52,
nitric acid will give a better yield than acetic acid because with acetic acid some material is converted into benzaldehyde by cleavage of the bond between two oxidized carbon atoms that is activated by both phenyl groups. Any help would be apprec..
