A student begins a kinetics experiment with a solution containing 0.050 % starch. At time zero (t = 0.00 min), the student adds

an enzyme that catalyzes the decomposition of starch. At t = 1.00 min, the concentration of starch has decreased to 0.028 %. Compute the average rate of disappearance of starch. Specify your answer in units of % starch/min

Answer:

- 0.022% starch/min

Explanation:

Initial Conc. = 0.050 %

Final conc. = 0.028 %

Time = 1 min

Rate of Reaction = Rate of disappearance  = Change in concentration of starch  / time

Rate of disappearance = [0.028 - 0.050 ] / 1

Rate of disappearance = 0.022 / 1 = - 0.022% starch/min

The negative sign denotes that the starch is disappearing.

What is the strongest type of intermolecular force between solute and solvent in each solution?
Elenna [48]

Hydrogen bonding is the strongest type of intermolecular force between solute and solvent.

<h3>What is Intermolecular Force ?</h3>

Intermolecular force is also called secondary force is the force of attraction between molecules. It acts between ions and atoms.

<h3>What is Hydrogen Bonding ?</h3>

Hydrogen bond is the attractive forces which binds the hydrogen atom of 1 molecule with electronegative atom of other molecule.

CH₃OCH₃ form hydrogen bonding and H₂O can also form hydrogen bonding.

Thus from the above conclusion we can say that Hydrogen bonding is the strongest type of intermolecular force between solute and solvent.
