The conversion of natural gas, which is mostly methane,into products that contain two or more carbon atoms, suchas ethane (C2H6), is a very important industrial chemicalprocess. In principle, methane can be converted into ethaneand hydrogen: 2 CH4(g)----->C2H6(g) + H2(g) In practice, this reaction is carried out in the presence ofoxygen: 2 CH4(g) + 12O2(g)---->C2H6(g) + H2O(g) (a) Calculate K for these reactionsat 25 °C and 500 °C.

I was told to repost this question, because I got the explanations for a-c. I just need d explained. 7. Sulfuryl chloride, SO2Cl2, is a highly reactive gaseous compound. When heated, it decomposes as follows: SO2Cl2 (g) ⇌ SO2 (g) + Cl2 (g). This decomposition is endothermic. A sample of 3.509 grams of SO2Cl2 is placed in an evacuated 1.00-L bulb and the temperature is raised to 375 K. a. What would be the pressure (in atm) in the bulb if no dissociation of the SO2Cl2(g) occurred? b. When the system has come to equilibrium at 375 K, the total pressure in the bulb is found to be 1.43 atm. Calculate the partial pressures of SO2, Cl2, and SO2Cl2 at equilibrium. c. Give the expression for the equilibrium constant (either Kp or KC) for the decomposition of SO2Cl2(g) at 375 K. Calculate the value of the equilibrium constant you have selected. d. If the temperature were raised to 500 K, what effect would this have on the equilibrium constant? Explain in 1-2 sentences.

Nitrosyl bromide, NOBr, can be formed from the reaction of NO and Br2: NO(g) + ½ Br2(g) NOBr K1 = 1.41 Nitrosyl bromide also readily decomposes to give N2, O2, and Br2: 2 NOBr(g) N2(g) + O2(g) + Br2(g) K2 = 1.05 x1030 Use these reactions to calculate Kc for the decomposition of nitric oxide, NO, into N2 and O2: 2NO(g) N2(g) + O2(g)
