Question

Give the units of $K_c$ for the formation of 1 mole of $N{H}_3$ from its constituents.

• A. gram mole${}^{-1}$
• B. mole gram${}^{-1}$
• C. litre mole${}^{-1}$
• D. mole litre${}^{-1}$

Answer 1

The correct option is C litre mole${}^{-1}$

$K_c=\frac{1}{{\left[{NH}_3\right]}^1}=\frac{1}{{\left[Conc\right]}^1}=\frac{1}{\left[mol{lit}^{-1}\right]}=lit{mol}^{-1}$
