x, y and z are 2, 5 and 16 respectively.

Option (C) is correct.

Explanation:

  • The half-equations of the reaction are

MnO4- → Mn2+

C2O42- → CO2  

  • Half balanced equations are:

( MnO4- 8H+ +5e- ----->Mn2+  + 4H2O ) x 2

( C2O4^2- -----> 2CO2 + 2e- ) x 5

Equating number of electrons, we get

2MnO4^2- + 16H+ + 10e- ---> 2Mn2+  + 8H2O

5C2O4^2-   ----> 10 CO2  + 10e-

On adding equations we get.

2MnO4^2-  + 5C2O4^2-  +  16H+ --- >  2Mn2+ + 2 x 5 CO2  + 16 / 2 H2O

Thus x, y and z are 2, 5 and 16 respectively.
