Xylene has three major isomers, m-xylene, o-xylene, and p-xylene. When o-xylene is passed over a Cryotite catalyst, the following elementary reactions are observed: The feed to the reactor is equimolar in both m-xylene and o-xylene (species A and B). For a total feed rate of 2 mol/min and reaction conditions below, plot the temperature and the

For the reaction CO 2 (g) + 2 SO 3 (g) CS 2 (g) + 4 O 2 (g) K = 0.0280 at 20 C. A mixture is prepared containing 2.0 M CO 2 , 3.0 M SO 3 , 0.30 M CS 2 and 1.0 M O 2 . Which of the following statements is true? Question 3 options: Q = 0.033; the concentration of CS 2 will decrease. Q = 0.028; the concentration of CS 2 will increase. Q = 0.017; the

A student performing this experiment on a 65.25 g piece of tin used 200 grams of water instead of the prescribed 100 grams. The initial temperature of the calorimeter water was 18.8 o C. The initial temperature of the metal was 99.6 o C. Tin has a known specific heat of 0.226 J/g o C. Determine the expected final temperature of the water/metal
