Verified Answer
Then factor Of FeS2 in the following reaction FeS2 → Fe3+ + SO2 ...
In redox reactions Eq.wt of oxidant or reductant is determined based on the no of electrons gained or lost by them during the reaction. Thus
E.W= M.W of oxidant or reductant/ no of electrons lost or gained.
FeS2------> Fe2O3+ SO2
E.W of FeS2. = MW/ 11
Reason:
Fe in FeS2 is in +2 state changing to +3 state of Fe2O3. So losing 1 electron. Out of two S atoms one is in — 2 state and another in zero state. But both are changing to +4 state of SO2. That means together they are losing 10 electrons (6 and 4 respectively). Therefore on the whole FeS2 is losing 11 electrons.

Then factor Of FeS2 in the following reaction FeS2 → Fe3+ + SO2 ...
**Explanation:**
The given reaction is:
FeS2 -> Fe3+ + SO2
We need to find the factor of FeS2 in this reaction.
To determine the factor, we look at the coefficient of FeS2 in the balanced chemical equation.
In this case, the coefficient of FeS2 is 1.
Therefore, the factor of FeS2 in the reaction is 1.
Option D (11) is incorrect as it does not match the factor of FeS2 in the reaction.
