If a scientist collected the steam (gaseous water) produced in a bunch of three liter soda bottles, how many soda bottles would they need? Make sure to balance the equation first. • C6H5OH(1)+O2(g) ----> CO2(g)+H2O(g)

4. Xylene can be produced from toluene as written schematically: CHAPTER 1 The Basics of Reaction Kinetics for Chemical Reaction Engineering 47 CH3 CH3 CH3 CH AG= 14.85 kJ mol" toluene ortho-xylene benzene CH3 CH3 CH, AG'= 10.42 kJ mol CH3 toluene meta-xylene benzene CH3 CH3 CH3 AG'= 15.06 kJ mol toluene benzene CH3 para-xylene The values of AG° were determined at 700 K. What is the equilibrium composition (including all xylene isomers) at 700 K and 1.0 atm pressure? Propose a method to manufacture para-xylene without producing significant amounts of either ortho- or meta-xylene.

Researchers first discovered in 1973 that chlorofluorocarbons (CFCS) were depleting the Earth's ozone layer when released into the atmosphere. Once they reach the stratosphere, CI is released from the CFCS molecules by interaction with UV light. Free Cl atoms are able to react with ozone in a catalytic cycle that converts Os3 into the more stable O2. It is estimated that a single Cl atom is able to react with_ 100000 O3 molecules. Although CFCS production was banned in 1996, there are still a substantial number of motor vehicle air conditioners (MVACS) that use CFC-12 (CF2CI2) as refrigerant. The average CFC-12 emission rate from operating MVACS has been estimated to be 59.5 mg per hour per vehicle (Zhang et al. Environ. Sci. Technol. Lett. 2017). How much chlorine, in kg, is added to the atmosphere in a year due to 100 million MVACS using CFC-12 as refrigerant?

Sketch a qualitative reaction energy diagram for a chemical reaction with and without a catalyst. Assume the uncatalyzed reaction is endothermic. Note: Because the sketches are only qualitative, the energies in them don't have to be exact. They only have to have the right relationship to each other. For example, if one energy is less than another, that fact should be clear in your sketch.

Consider a chemical reaction between compound A and compound B. The reaction proceeds via a multi-step mechanism involving several intermediates and transition states. The overall reaction is exothermic, but one of the intermediate steps is endothermic. Explain how the endothermic intermediate step can still be consistent with the overall exothermic nature of the reaction.

Determine the reactants and reaction conditions in the correct order to complete the next conversion.
