Calculate the reaction rate for each of the three trials. Determine the order of the reaction with respect to NO2.
Bomb Calorimeter, gross heat of combustion, In the following experiment 1.1651g of benzoic acid (6318 cal/gm) produced a net corrected temperature rise of 3.047C, also 8 cm (2.3 cal/cm) of fuse wire were consumed in the firing.
Provide some diagnostically useful differences you would expect in the IR spectra between starting materials and product for the reaction you carried out (e.g. if I was asked this regarding the oxidation of cyclohexanol to cyclohexanone
