COMEDK · Chemistry · 7. Chemical Equilibrium
The equilibrium constant, \(K_C\) for \(3 \mathrm{C}_2 \mathrm{H}_2(\mathrm{~g}) \rightleftharpoons \mathrm{C}_6 \mathrm{H}_6(\mathrm{~g})\) is \(4 \mathrm{~L}^2 \mathrm{~mol}^{-2}\). If the equilil rium concentration of benzene is \(0.5 \mathrm{~mol}^{-1}\) than what is the value of concentration of ethylene?
- A \(0.05 \mathrm{~mol} / \mathrm{L}\)
- B \(0.5 \mathrm{~mol} / \mathrm{L}\)
- C \(0.25 \mathrm{~mol} / \mathrm{L}\)
