When 4.0 mol of NH3(g) is introduced into a 2.0 L

 

 

When 4.0 mol of NH3(g) is introduced into a 2.0 L

2NH3(g) ⇌ N2(g) + 3H2(g)

NH3(g) at equilibrium decreases to 2.0 mol

초기 [NH3]

= 4.0 mol / 2.0 L = 2.0 M

............. 2NH3(g) ⇌ N2(g) + 3H2(g)

평형(M): 2.0–2x ....... x ......... 3x

 

 

 

평형 [NH3]

= 2.0 mol / 2.0 L = 1.0 M

 

 

 

2.0 – 2x = 1.0

 

2x = 1.0

 

x = 1.0 / 2 = 0.50 M

 

 

 

답:

[NH3] = 1.0 M

[N2] = x = 0.50 M

[H2] = 3x = 3 × 0.50 = 1.5 M
