Question 1

In the gas phase, methyl isocyanate (CH3NC) isomerizes to acetonitrile (CH3CN),
         H3C–N≡C (g) H3C–C≡N (g)
with ΔH° = –89.5 kJ/mol and ΔG° = – 73.8 kJ/mol at 25°C.  Find the equilibrium constant for this reaction at 100°C.
◦ 1.68 × 10–10

◦ 5.96 × 109

◦ 2.16 × 1010

◦ 4.63 × 10–11

◦ 8.64 × 1012


Question 2

Kw for the auto-ionization of water, H2O(l) → H+(aq) + OH (aq), is 1.0 × 10–14.  What are the signs (+/–) of ΔS° and ΔH° for the reaction at 25°C?
◦ ΔS° = (+) and ΔH° = (+)
◦ ΔS° = (+) and ΔH° = (–)
◦ ΔS° = (–) and ΔH° = (+)
◦ ΔS° = (–) and ΔH° = (–)

Did you know?

Pregnant women usually experience a heightened sense of smell beginning late in the first trimester. Some experts call this the body's way of protecting a pregnant woman from foods that are unsafe for the fetus.

Did you know?

Vital signs (blood pressure, temperature, pulse rate, respiration rate) should be taken before any drug administration. Patients should be informed not to use tobacco or caffeine at least 30 minutes before their appointment.

Did you know?

By definition, when a medication is administered intravenously, its bioavailability is 100%.

Did you know?

Approximately 15–25% of recognized pregnancies end in miscarriage. However, many miscarriages often occur before a woman even knows she is pregnant.

Did you know?

Automated pill dispensing systems have alarms to alert patients when the correct dosing time has arrived. Most systems work with many varieties of medications, so patients who are taking a variety of drugs can still be in control of their dose regimen.
