Question 1

For the production of NO2, Kc = [NO2]2/[NO]2[O2].  At equilibrium in a 2.50 L container, there are 3.00 mol NO, 4.00 mol O2 and 22.0 mol NO2. The value of Kc is ________.
◦ 13.4
◦ 33.6
◦ 5.38
◦ 0.0116
◦ 3.75

Question 2

For the reaction 2 A(g) B(g) + C(g), Kc= 1.25 at 300 K. If a 1.00 L mixture contains 0.619 mol A, 0.693 mol B, and 0.689 mol C at 300 K, will the mixture be in equilibrium? If not, in what direction will a net reaction occur?
◦ Yes, reaction is at equilibrium.
◦ No, net reaction proceeds to the left.
◦ No, net reaction proceeds to the right.
◦ No, but there is no net reaction.
◦ Yes, net reaction proceeds to the right

Every flu season is different, and even healthy people can get extremely sick from the flu, as well as spread it to others. The flu season can begin as early as October and last as late as May. Every person over six months of age should get an annual flu vaccine. The vaccine cannot cause you to get influenza, but in some seasons, may not be completely able to prevent you from acquiring influenza due to changes in causative viruses. The viruses in the flu shot are killed—there is no way they can give you the flu. Minor side effects include soreness, redness, or swelling where the shot was given. It is possible to develop a slight fever, and body aches, but these are simply signs that the body is responding to the vaccine and making itself ready to fight off the influenza virus should you come in contact with it.
