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.

If a small weather balloon with a volume of 40.0 L at a pressure of 1.00 atmosphere was deployed at the edge of Typhoon Odessa,
Feliz [49]

Answer: The volume of the balloon at the center of the typhoon is 41.7L.

Note: The complete question is given below;

If a small weather balloon with a volume of 40.0 L at a pressure of 1.00 atmosphere was deployed at the edge of Typhoon Odessa, what was the volume of the balloon when it reached the center?

The severity of a tropical storm is related to the depressed atmospheric pressure at its center. In August 1985, Typhoon Odessa in the Pacific Ocean featured maximum winds of about 90 mi/hr and pressure that was 40.0 mbar lower at the center than normal atmospheric pressure. In contrast, the central pressure of Hurricane Andrew (pictured) was 90.0 mbar lower than its surroundings when it hit south Florida with winds as high as 165 mi/hr.

Explanation:

Since no temperature changes were given, it is assumed to be constant. Therefore, Boyle's law which describes the relationship between pressure and volume is used to determine the new volume at the center of Typhoon Odessa. Mathematically, Boyle's law states that; P1V1 = P2V2

Assuming 1atm = 1 bar, 1mbar = 0.001atm, 40mbar = 0.040atm

P1 = 1.0atm, V1 = 40.0L, P2 = 1atm - 0.040atm = 0.960atm, V2 = ?

Using P1V1 = P2V2

V2 = P1V1/P2

V2 = 1.0 * 40.0 / 0.96

V2 = 41.67L

Therefore, the volume of the balloon at the center of the typhoon is 41.7L.
