Answer to Question #169451 in General Chemistry for Phyroe

Question

Write equilibrium expression for the following reactants (reactants and products are all gases):

(a) N3 + 3H2⇌2NH3

(b) 4HCl + O2⇌2H2O

(c) CH4 + 2O2⇌CO2 + 2H2O

(d) 3C2H2⇌C6H6

(e) 2CO2⇌2CO + O2

Answer 1

According to the equilibrium expression:

aA + bB = cC + dD

K_eq = [C]^c[D]^d / [A]^a[B]^b

From here:

(a) K_eq = [NH₃]² / [N₃][H₂]³

(b) K_eq = [H₂O]² / [HCl]⁴[O₂]

(c) K_eq = [CO₂][H₂O]² / [CH₄][O₂]²

(d) K_eq = [C₆H₆] / [C₂H₂]³

(e) K_eq = [CO]²[O₂] / [CO₂]²
