Consider the following reaction: x   MnO 4 - + y   C 2 O 4 2 - + zH + ⟶ x   Mn 2 + + 2 y   CO 2 + z 2 H 2 O The values of x, y and z in the reaction are, respectively:

Options

  1. A2 , 5   and   16
  2. B5 , 2   and   8
  3. C5 , 2   and   16
  4. D2 , 5   and   8

Correct answer

A. 2 , 5   and   16

Step-by-step solution

C 2 O 4 2 - ⟶ 2 CO 2 + 2 e - ] × 5 MnO 4 - + 8 H + + 5 e - ⟶ Mn 2 + + 4 H 2 O ] × 2 ----------------------------------------------------------------------------------- 2 MnO 4 - + 1 6 H + + 5 C 2 O 4 2 - ⟶ 1 0 CO 2 + 2 Mn 2 + + 8 H 2 O MnO 4 - ⇒ x = 2 C 2 O 4 2 - ⇒ y = 5 H + ⇒ z = 1 6
