Question 1

Determine the equilibrium constant for the following reaction at 498 K:

2 Hg(g) + O2(g) → 2HgO(s)ΔrH° = -304.2 kJ mol-1; ΔrS° = -414.2 J K-1 mol-1

◦ 5.34 × 10-11
◦ 2.31 × 10-22
◦ 1.87 × 1010
◦ 8.10 × 1031
◦ 4.33 × 1021

Question 2

Determine the equilibrium constant for the following reaction at 655 K:

HCN(g) + 2H2(g) → CH3NH2(g)ΔrH° = -158 kJ mol-1; ΔrS°= -219.9 J K-1 mol-1

◦ 2.51 × 10-13
◦ 13.0
◦ 3.07 × 1011
◦ 3.26 × 10-12
◦ 3.99 × 1012

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.

Did you know?

You should not take more than 1,000 mg of vitamin E per day. Doses above this amount increase the risk of bleeding problems that can lead to a stroke.

IgA antibodies protect body surfaces exposed to outside foreign substances. IgG antibodies are found in all body fluids. IgM antibodies are the first type of antibody made in response to an infection. IgE antibody levels are often high in people with allergies. IgD antibodies are found in tissues lining the abdomen and chest.
