The volume of a balloon is 2.74 Lat 24.30 C. The balloon is heated to 43.80 C. If the pressure is held constant what is the new volume of the balloon? (4 pts) a 2.92 L 2.57 L b. c. 1.52 L d. 4.94 L e. 0.0403 L in Which of the following will have the largest (4 pts) A mol of SO, at 500 K A mol of H, at 200 K A mol of O, at 400 K A mol of He at 100 K A mol of Ar at 350 K. Copper has a max of 635 nm in water to give it a blue color. If a standard solutions in a 1 cm path length of 0.25 M has an absorbance of 0.70 and 0.125 has an absorbance of 0.35, what is the concentration of a solution that has an absorbance of 0.53? (4 pts) 1.5 M b. 0.19 M c. 0.25 M d. 0.37 M c. 0.60 M 2) The rate constant for a reaction is 4.7 10-3-1 at 250 C, if the activation energy is 33.6 kJ/mol, what is at 750 C? (4 pts) a. 6.7*10-45-1 b. 4.7*10-35-1 Temperature doesn't change the rate constant. c. 3.3*10-24-1 The rate constant will decrease but you cant solve mathematically. The rate constant will increase but you cant solve mathematically. What is true for a heterogeneous catalyst? (4 pts) It is in a different phase than the reaction mixture. It will change the activation energy. It will change the rate typically through a change in mechanism. 2 out of the three above are true. All a-c are true.
