Question 1

Hydrogen peroxide (H2O2) decomposes according to the equation
         H2O2(l) → H2O(l) + 1/2O2(g).
Calculate Kp for this reaction at 25°C.  (ΔH° = –98.2 kJ/mol, ΔS° =  70.1 J/K·mol)
◦ 1.3 × 10–21

◦ 20.9

◦ 7.5 × 1020

◦ 8.6 × 104


Question 2

In the gas phase, formic acid forms a dimmer, 2HCOOH(g) (HCOOH)2(g).  For this reaction, ΔH° = –60.1 kJ/mol and ΔG° = –13.9 kJ/mol at 25°C.  Find the equilibrium constant (Kp) for this reaction at 75 °C.

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.

Over time, chronic hepatitis B virus and hepatitis C virus infections can progress to advanced liver disease, liver failure, and hepatocellular carcinoma. Unlike other forms, more than 80% of hepatitis C infections become chronic and lead to liver disease. When combined with hepatitis B, hepatitis C now accounts for 75% percent of all cases of liver disease around the world. Liver failure caused by hepatitis C is now leading cause of liver transplants in the United States.
