Question 1

The isomerization of cyclopropane to propene follows first-order kinetics.
         
At 700 K, the rate constant for this reaction is 6.2 × 10–4 min–1.  How many minutes are required for 10.0% of a sample of cyclopropane to isomerize to propene?
◦ 16,100 min
◦ 170 min
◦ 3,710 min
◦ 1.43 × 10–3 min
◦ 1,120 min

Question 2

The isomerization of methyl isocyanide, CH3NC → CH3CN, follows first-order kinetics. The half-lives were found to be 161 min at 199°C and 12.5 min at 230°C.  Calculate the activation energy for this reaction.
◦ 6.17 × 10–3 kJ/mol
◦ 31.4 kJ/mol
◦ 78.2 kJ/mol
◦ 124 kJ/mol
◦ 163 kJ/mol

Most strokes are caused when blood clots move to a blood vessel in the brain and block blood flow to that area. Thrombolytic therapy can be used to dissolve the clot quickly. If given within 3 hours of the first stroke symptoms, this therapy can help limit stroke damage and disability.

For about 100 years, scientists thought that peptic ulcers were caused by stress, spicy food, and alcohol. Later, researchers added stomach acid to the list of causes and began treating ulcers with antacids. Now it is known that peptic ulcers are predominantly caused by Helicobacter pylori, a spiral-shaped bacterium that normally exist in the stomach.

Many people have small pouches in their colons that bulge outward through weak spots. Each pouch is called a diverticulum. About 10% of Americans older than age 40 years have diverticulosis, which, when the pouches become infected or inflamed, is called diverticulitis. The main cause of diverticular disease is a low-fiber diet.
