For a reaction of order n , the unit of the rate constant is :

Options

  1. Amol 1 - n L 1 - n s
  2. Bmol 1 - n L 2 n s - 1
  3. Cmol 1 - n L n - 1   s - 1
  4. Dmol 1 - n L 1 - n s - 1

Correct answer

C. mol 1 - n L n - 1   s - 1

Step-by-step solution

Rate = k [ A ] n comparing units ( mol / ℓ ) sec = k mol ℓ n ⇒ k = mol ( 1 - n ) ℓ ( n - 1 ) s - 1
