For the gaseous reaction C 2 H 4 + H 2 ⇌ C 2 H 6 The equilibrium constant, has the units

Options

  1. Am o l 2 d m - 3
  2. Bd m 3 m o l - 1
  3. Cd m - 3 m o l - 1
  4. Dm o l d m - 3

Correct answer

B. d m 3 m o l - 1

Step-by-step solution

Units of K C = [ U n i t o f c o n c e n t r a t i o n ] Δ n g Δ n g = sum of gaseous products – sum of gaseous reactants Δ n g = 1 - 2 = - 1 = [ m o l d m - 3 ] - 1 = d m 3 m o l - 1 .
