Question
Given below are two statements.
Statement I: The choice of reducing agents for metals extraction can be made by using Ellingham diagram, a plot of $\Delta \mathrm{G}$ vs temperature. Statement II: The value of $\Delta \mathrm{S}$ increases from left to right in Ellingham diagram. In the light of the above statements, choose the most appropriate answer from the options given below:
Select the correct option:
A
Both Statement I and Statement II are true
B
Statement I is false but Statement II is true
C
Both Statement I and Statement II are false
D
Statement I is true but Statement II is false
✓ Correct! Well done.
✗ Incorrect. Try again or view the solution.
Solution
Given statement is false as in a nuclear power process, one element is used to reduce the cost of another metal. Any element will reduce the cost of other metal which is below it in the Ellingham diagram because the more reactive element can remove oxygen.
