A) 75%
B) 45%,
C) 15%
D) 35%
Correct Answer: C
Solution :
Oxidation number of Fe in wustite \[138\text{ }cal/deg\] It is an intermediate value in between two oxidation states of Fe, Fe(II) and Fe (III). Suppose the percentage of Fe (III) be x, then \[13.75\text{ }cal/deg\] \[18.28eu\] or \[23.41\text{ }eu\] Hence, wustite is the mixture of 15% Fe(III) and 85% Fe(II).You need to login to perform this action.
