The Kp for the following equilibrium system is 4.31 x 10‒4 at 375C : N2(g) + 3H2(g) ↔ 2NH3(g).
If 0.862 atm of N2 and 0.373 atm of H2 were mixed in a constant-volume flask and heated to 375C, which of the following would be closest to the equilibrium partial pressure of NH3 ?

(1) 0.860 atm (2) 4.40 x 10‒3 atm (3) 2.75 x 10‒4 atm (4) 0.366 atm (5) 1.09 x 10‒2 atm
