Q14 / 90 · JEE Main 2021 (27 Jul Shift 1) · Chemistry

The statement that is $INCORRECT$ about Ellingham diagram is

Correct answer
A
provides idea about the reaction rate.
B
provides idea about free energy change.
C
provides idea about changes in the phases during the reaction.
D
provides idea about reduction of metal oxide.

Solution

Ellingham diagram is a plot between

Δ G °

and

T

and does not give any information regarding rate of reaction

Hence, the correct answer is option: 'A'.
