Ellingham diagram represents:

A

change of `DeltaG` with temperature

B

change of `DeltaH` with temperature

C

change `DeltaG` will pressure

D

change of `(DeltaG-T DeltaS)` will temperature.

Text Solution

Verified by Experts

The correct Answer is:
A
Ellingham diagram helps us in predicting the feasibility of thermal reduction of an ore. The feasibility is depected by `DeltaG` at a given temperature. Hence, it is a plot of `DeltaG^(@)` vs T.
