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:
Correct Option: , 4
Given statement-I is true as in a number of processes, one element is used to reduce the oxide of another metal. Any element will reduce the oxide of other metal which lie above it in the Ellingham diagram because the free energy change will become more negative.
Given statement-II is false as the value of $\Delta \mathrm{S}$ is decreases from left to right in Ellingham diagram.
