Question 1

The reaction has the following rate law:
   
After a period of 2.7 × 103 s, the concentration of NO falls from an initial value of 2.8 × 10–3 mol/L to 2.0 × 10–3 mol/L. What is the rate constant, k?

◦ 1.5 × 10–7M–1·s–1

◦ 5.3 × 10–2M–1·s–1

◦ 3.2 × 10–1M–1·s–1

◦ 1.2 × 10–4M–1·s–1

◦ 2.6 × 10–2M–1·s–1


Question 2

The reaction is known to be zero order in A with a rate constant of 5.0 × 10–2 mol/L s at 25°C. An experiment was run at 25°C where [A]0 = 1.7 × 10–3M. The half-life for the reaction is

◦ 1.7 × 10–2s
◦ 1.7 × 102s
◦ 5.0 × 10–2 s
◦ 3.4 × 10–4s
◦ None of these are correct.

The human body's pharmacokinetics are quite varied. Our hair holds onto drugs longer than our urine, blood, or saliva. For example, alcohol can be detected in the hair for up to 90 days after it was consumed. The same is true for marijuana, cocaine, ecstasy, heroin, methamphetamine, and nicotine.

Though methadone is often used to treat dependency on other opioids, the drug itself can be abused. Crushing or snorting methadone can achieve the opiate "rush" desired by addicts. Improper use such as these can lead to a dangerous dependency on methadone. This drug now accounts for nearly one-third of opioid-related deaths.

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.
