Question 4 Nitrogen creates various compounds with oxygen, some of them are main components in photochemical smog. Have a look on the following table: 1. Write the balanced equation for the creation in equilibrium of N2O4(g) from NO2(g). 2. Calculate H and Grfor for the reaction you just wrote. Regarding entropy, discuss qualitatively - what happens to S here? 3. What is the equilibrium constant of pressures, Kp, for this reaction at room temperature? 4. Use the ideal gases equation PV=nRT to show that the equilibrium constant of pressure and the equilibrium constant of concentrations have the following relatic Kp=(RT)nKc What is the equilibrium constant in terms of concentrations for this reaction? to the total change in moles during the reaction). 5. Knowing that NO2(g) concentration in atmosphere at 25C is 1.2109M. What is th concentration of N2O4(g) ? 6. Try to describe what happens to the equilibrium with temperature (Hint: use you answer to 2). When does the concentration of NO2 is higher? During summer or winter
