Reaction Kinetics. The Bromination of Acetone
... Determination of the B constant: The constant B of equation [10] is determined by measuring the absorbance of at least three solutions of known bromine concentration. At room temperature, prepare one solution by pipetting 10.0 ml of stock 0.02 M Br2 into a clean 125-ml Erlenmeyer flask. Add 10.0 ml ...

... To cause a molecule to dissociate into its atoms, we must supply the molecule with enough energy to induce such vigorous vibrations that its atoms fly apart, an endothermic process (∆H > 0). To assess the entropy change, we first note that a molecule has a greater number of available energy levels t ...
