You will start with 500 mg of one of isoamyl acloho to make isoamyl acetate. While the alcohols are liquids, we will measure them by mass directly on the balance, not by volume (i.e. the density of the alcohol will not be used; pretend the alcohol is a solid). Acetic acid (or propionic acid) will be measured by volume. Determine the volume of acetic acid (or propionic acid) to add that will correspond to 4.0 molar equivalents based on mmols of starting alcohol. 5.67 mmol of alcohol starting material. Melocular weight of starting material 88.15 mg/mmol. Acetic acid is 60.05mg/mmol.
Calculate E when 770.0 g of CH3OH(g) completely reacts at a constant temperature of 300 K and constant pressure of 0.95 atm. R = 8.314 J/mol*K and R = 0.08206 atm*L/mol*K.
the S for the system is predicted to be negative, so therefore the ?S for the surroundings must be positive to a greater extent so that the the net S for the universe is positive
