1. The problem statement, all variables and given/known data At 25°C, Kp = 1x10-31 for the reaction below. N2(g) + O2(g) <--> 2 NO(g) (a) Calculate the concentration of NO (in molecules/cm3) that can exist in equilibrium in air at 25°C. In air PN2 = 0.8 atm and PO2 = 0.2 atm. 2. Relevant equations ?? 3. The attempt at a solution I have calculated the partial pressure of NO to be 1.26x10-16 but I do not know how to convert to Kp from this. Any help would be greatly appreciated!
