Question

In air at 25 °C and 1.00 atm, the N2 concentration is 0.01 M and the O2 concentration is 0.033 M. The reaction

N2(g) + O2(g) ⇄ 2NO(g)

has Kc = 4.8 x 10-31 at 25 °C.

Taking the N2 and O2 concentrations given above as initial values, calculate the equilibrium NO concentration that should exist in our atmosphere from this reaction at 38 °C, Kc = 1.0E-29.

Make simplifying assumptions in your calculations. (Express your answer in scientific notation.)
[NO] = ____________  M
