Question

At 25° C, Kp < 1 × 10-31 for the reaction N2(g) + O2(g) ⇌ 2NO(g)
a. Calculate the concentration of NO (in molecules/ cm3) that can exist in equilibrium in air at 25oC. In air PN2 = 0.8 atm and PO2 = 0.2 atm.
b. Typical concentrations of NO in relatively pristine environments range from 108 molecules/ cm3 to 1010 molecules/ cm3. Why is there a discrepancy between these values and your answer to part a?
