Question 1

The thermal decomposition of acetaldehyde, CH3CHO → CH4 + CO, is a second-order reaction.  The following data were obtained at 518°C.
 
time, s
Pressure CH3CHO,  mmHg
 
0
364
 
42
330
 
105
290
 
720
132
Based on the data given, what is the half-life for the disappearance of acetaldehyde?

◦ 1.5 × 105 s
◦ 410 s
◦ 5.4 × 107 s
◦ 520 s
◦ 305 s

Question 2

Use the following data to determine the rate law for the reaction shown below.
         2NO + H2→ N2O + H2O
Expt. #
[NO]0
[H2]0
Initial rate
1
0.021
0.065
1.46 M/min
2
0.021
0.260
1.46 M/min
3
0.042
0.065
5.84 M/min
 

◦ rate = k[NO]
◦ rate = k[NO]2

◦ rate = k[NO][H2]
◦ rate = k[NO]2[H2]
◦ rate = k[NO]2[H2]2

Adults are resistant to the bacterium that causes Botulism. These bacteria thrive in honey – therefore, honey should never be given to infants since their immune systems are not yet resistant.

Walt Disney helped combat malaria by making an animated film in 1943 called The Winged Scourge. This short film starred the seven dwarfs and taught children that mosquitos transmit malaria, which is a very bad disease. It advocated the killing of mosquitos to stop the disease.

Immunoglobulin injections may give short-term protection against, or reduce severity of certain diseases. They help people who have an inherited problem making their own antibodies, or those who are having certain types of cancer treatments.

Did you know?

A serious new warning has been established for pregnant women against taking ACE inhibitors during pregnancy. In the study, the risk of major birth defects in children whose mothers took ACE inhibitors during the first trimester was nearly three times higher than in children whose mothers didn't take ACE inhibitors. Physicians can prescribe alternative medications for pregnant women who have symptoms of high blood pressure.

A recent study has found that following a diet rich in berries may slow down the aging process of the brain. This diet apparently helps to keep dopamine levels much higher than are seen in normal individuals who do not eat berries as a regular part of their diet as they enter their later years.
