Answer to Question #316414 in Chemistry for decky

Question

Calculate K for the reaction :

2A + B <----> C + D

If at equilibrium, A = 0.4 mols/liter, mols/liter, B = 0.5 mols per liter. C = 0.3 mols per liter, and D = 0.8 mols per liter.

Answer 1

Solution:

The chemical reaction:

2A + B ⇌ C + D

The equilibrium constant expression for the reaction system:

[A] = 0.4 mol/L

[B] = 0.5 mol/L

[C] = 0.3 mol/L

[D] = 0.8 mol/L

Therefore,

K = (0.3 × 0.8) / (0.5 × 0.4²) = (0.24) / (0.08) = 3.0

K = 3.0 L/mol

Answer: The equilibrium constant (K) for the reaction is 3.0 liter/mol
