QJEEM20Ch16a0: JEE Main 2020 Chemistry - Class 11 JEEM20Ch16a0 Solution: Consider the following equations : 2Fe 2+ + H 2 O 2 xA + yB (in …

Consider the following equations :
2Fe2+ + H2O2 →\to xA + yB
(in basic medium)
2MnO4- + 6H+ + 5H2O2 →\to x'C + y'D + z'E
(in acidic medium)
The sum of the stoichiometric coefficients x, y, x', y', and z' for products A, B, C, D and E, respectively, is ______.

Step-by-Step Verified Solution

2Fe2+ + H2O2 →\to 2Fe3+ + 2OH–

2MnO4- + 6H+ + 5H2O2 →\to 2Mn2+ + 8H2O + 5O2

∴\therefore x + y + x' + y' + z' = 19
