Answer:
0.33 mol of Fe₂O₃
Explanation:
For the reaction given in the question -
Fe₂O₃ + 5 C + 3O₂ → 2 Fe + 5 CO₂
Balancing the above reaction ,
2Fe₂O₃ + 5 C + 3O₂ → 2 Fe + 5 CO₂
According to the above balanced reaction ,
<u>2 mol of Fe₂O₃ will react with 5 mol of C and 3 mol of O₂ to give 2 mol of Fe and 5 mol of CO₂ .</u>
Hence ,
2 mol of Fe₂O₃ will react with 3 mol of O₂
or ,
3 mol of O₂ ------ 2 mol of Fe₂O₃
Using unitary method ,
1 mol of O₂ ------ 2 / 3 mol of Fe₂O₃
From the question , for 0.49 mol of O₂ ,
0.49 mol of O₂ ------- 2 / 3 * 0.49 mol of Fe₂O₃ = 0.33 mol of Fe₂O₃

The factors that affect the rate of solution formation are capable of either increasing the rate of solution formation or decreasing it.
<h3>Factors that affect the rate of solution formation</h3>
The rate of solution formation from a chemical reaction depends on the following factors:
- Quantity of solute and solvent: The solute should be in less quantity and solvent should be more in quantity to dissolve the solute. This will enhance the formation of solution
- The size of the solute particles: When the solute particles are in smaller sizes, they react faster with the solvent to form solutions.
- The temperature of solvent: In increased temperature, the solute reacts faster with the solvent.
Therefore, the factors that affect the rate of solution formation are capable of either increasing the rate of solution formation or decreasing it.

C2H2O4 C2HO4- + H+
0.175 - x x x + y
C2HO4- c2o42– + H+
x - y y x + y
K2 = (y) (x +y) / (x-y)
As, y << x
So, K2 = (y) (x) / (x)
K2 = y =6.1 × 10^–5
Hence, concentration of (c2o42–) 6.1 × 10^–5 M
