Which one of the following is incorrectly matched.

Answer:

Solution:

The incorrectly matched option is (a).

In the thermite process, aluminum reduces iron(III) oxide:

$F e_{2} O_{3} + 2 A l \to A l_{2} O_{3} + 2 F e$

But option (a) shows the reverse reaction:

$2 F e + A l_{2} O_{3} \to 2 A l + F e_{2} O_{3}$

which is not the thermite process.

Options (b) Van Arkel process, (c) CO reduction of iron oxide, and (d) Serpek's process are correctly matched.
