Question

For which system does the equilibrium constant, K, have the units of (concentration)²?
Options
A H₂ + I₂ ⇌ 2HI
B H₂O + CH₃CO₂CH₂CH₃ ⇌ CH₃CH₂OH + CH₃CO₂H
C CH₄ + H₂O ⇌ CO + 3H₂
Correct Answer
D 2NO₂ ⇌ N₂O₄
Correct Answer

Option C is the correct answer.

Detailed Explanation

Units of Kc are M^(Δn). For CH₄ + H₂O ⇌ CO + 3H₂, Δn = (1+3) - (1+1) = 4 - 2 = 2, so units are M².

Hint

Δn = moles gaseous products - moles gaseous reactants.
