In the Ostwald process for oxidizing ammonia, a variety of products is possible-N2, N2O, NO, and NO2- depending on the conditions. One possibility is NH3(g) +O2(g) NO(g) +H20(g) Kp = 2.11 x 1019 at 700 K %3D For the decomposition of NO, at 700 K, 1 NO2(g) NO(g) +02(g) Kp = 0.524 2

The Kp for 3A(g) + 4B(g) = 2C(g) + 3D(s) is 4.90 x 10-4 at 300C. Determine the Kc for this reaction at the same temperature.

A tiny sample of an aqueous solution of two substances R and P is sketched below, as if it was under an imaginary microscope so powerful that individual molecules could be seen. (The water molecules are not shown.) R P R and P can interconvert. That is, R can turn into P, and P can turn back into R: R(aq) P(ag) K= The equilibrium constant K for this equilibrium is Predict the number of R and P molecules in this sample when the interconversion reaches equilibrium. number of R molecules: number of P molecules:| Check Privacy Center Accessibility Explanation 02022 McGraw Hill LLC.

Consider the reactions and their respective equilbrium constants: NO(g) + 1/2BR(g) > NOBR(g)   KP = 5.3 2NO(g) > N2(g) + O2(g)             KP = 2.1 x 1030 Use these reactions and their equilbrium constants to predict the equlibrium constant for the following reaction: N2(g) + O2(g) + Br2(g) > 2NOBR(g)

12. Consider the chemical reaction 2HCl(g) H2(g) + Cl2(g). It contains 8.0 mol HCI, 0.20 mol H₂ and 0.40 mol Cl₂ in a 1.00 L flask at equilibrium. Calculate Kc and Kp at 300. °C. for the reaction.

For the equilibrium reaction.   2IBr (g) I2 (g) + Br2 (g) Kc=.0085.  If .025 M of IBr is introduced to an empty flask and allowed to reach equilibrium, calculate the final concentrations of all components.   Consider the decomposition reaction at 555 K   4POCl3 (g)    P4  (g) + 2O2  (g) + 6Cl2  (g)   If .450 atm of POCl3 is introduced to an otherwise empty flask and the reaction is allowed to reach equilibrium, the final total pressure is .850 atm.  Find Kp and Kc.
