Understanding reactions involving normal components of air is essential for solving problems 16. dealing with atmos pheric pollution. Here is a reaction sequence involving N2 and O2, the most abundant gases in air. Nitrogen dioxide is a toxic pollutant that contributes to photochemical smog. Using the reactions given below, determine the equilibrium constant for the following reaction: N2(0)202g) 2NO2 (9) Ke ? N2(g) O2(g) 2NO () Ke= 4.3 x 10-25 NO2(g) NO (g) O2(g) Ke=1.25x 10 5
Please answer #3 and #4 only Photochemical Smog Photochemical smog is a type of air pollution produced when sunlight acts upon motor vehicle exhaust gases, such as nitrogen oxides (e.g., NO, NO:) to form harmful substances such as ozone (0). These substances participate in a reaction cycle that determines the concentration of pollutants at different times during the day. Ozone Formation: NO:(), is formed by chemical reactions involving N2(g) and O-() at the high temperatures inside internal combustion engines in...
**SHORT QUESTION** Hello newfound chemists! Again, we are continuing our trek into the study of chemical principles, but now, we are evaluating the significance attached with cars and the emissions that they release. Knowing what is released from these emissions is essential to moving forward and ensuring that holistically, there is an understanding of the danger in the air. Nitrogen dioxide, NO2, is an atmospheric pollutant from automobile emissions. Consider the endothermic formation of NO2 as shown below, with the...
Help please! Show work xercise 14.16 thodynamic 2. The equilibrium constant for the following reaction is called the fluoride: constant for the following reaction is called the "solubility product of calcium CaF2(s) - Ca2+(aq) + 2F (aq) K = K = 3.2 x 10-11 a write an expression for the equilibrium constant of this reaction in terms of concentrations. why do you suppose we call this a solubility product instead of a solubility quotient or ratio (b) Calculate the equilibrium...
please show work! thank you 1. What is the equilibrium constant expression for each reaction below? a. 3NaBr(aq) + CuN(s) → CuBr3(aq) + Na3N (aq) b. CH4(9) + 2O2(g) → CO2 + 2H2O(1)

A buffer solution is able to maintain a constant pH when small amounts of acid or base are added to the buffer. Consider what happens when 1 mL of a 5 M solution is added or 0.005 mol of HCl are added to a 100.0 mL solution acetic acid buffer that contains 0.0100 mol of Acetic acid, HC,H,O,, and 0.0100 mol of sodium acetate, NaC,H,O,. The initial concentration of both the acid and the base are 0.0100 mol/ 0.1000 L...
