Final answer:
The equilibrium constant (Keq) for the reaction A + 2B ⇌ C, with the given equilibrium concentrations, is calculated to be 250.
Step-by-step explanation:
To determine the equilibrium constant (Keq) for the reaction A + 2B ⇌ C, given the equilibrium concentrations (A) 0.06mole/liter, (B) 0.12mole/liter, and (C) 0.216mole/liter, we use the equilibrium expression:
Keq = [C]/([A][B]2)
Substituting the provided equilibrium concentrations:
Keq = (0.216)/ (0.06*(0.12)2)
After calculating:
Keq = (0.216)/ (0.06*0.0144)
Keq = (0.216)/ (0.000864)
Keq = 250
