Chapter 14.5, Problem 11PE

At 430°C, the equilibrium constant (K_P) for the reaction

$2\text{NO}(g)+{\text{O}}_2(g)\rightleftharpoons 2{\text{NO}}_2(g)$

is 1.5 × 10⁵. In one experiment, the initial pressures of NO, O₂, and NO₂ are 2.1 × 10⁻³ atm, 1.1 × 10⁻² atm, and 0.14 atm, respectively. Calculate QP and predict the direction that the net reaction will shift to reach equilibrium.
