Chapter 15, Problem 15.113QP

The equilibrium constant K_p for the following reaction is 4.31 × 10⁻⁴ at 375°C.

${\text{N}}_{\text{2}}\left(g\right)+{\text{3H}}_{\text{2}}\left(g\right)\rightleftarrows 2{\text{NH}}_{\text{3}}\left(g\right)$

In a certain experiment a student starts with 0.862 atm of N₂ and 0.373 atm of H₂ in a constant-volume vessel at 375°C. Calculate the partial pressures of all species when equilibrium is reached.
