KCET2018ChemistryRedox Reactions
For the redox reaction ( xMnO ₄⁻+ yH ₂ C ₂ O ₄+ zH ⁺ mMn ²⁺+ nCO ₂+ pH ₂ O ) The values of ( x , y , m ) and ( n ) are
Options
- A( 10,2,5,2 )
- B( 2,5,2,10 )
- C( 6,4,2,5 )
- D( 3,5,2,10 )
Correct answer
B. ( 2,5,2,10 )
Step-by-step solution
The balance chemical equation is, ( 2 MnO ₄+5 H ₂ C ₂ O ₄+6 H ⁺ 2 Mn ²⁺+10 CO ₂+8 H ₂ O ) Therefore, the value of stoichiometric constants is, ( x=2 ; y=5 ; m=2 ) and ( n=10 )
