Solution

The temperature range in which is lesser than, Mg can reduce SiO_{2 to} Si.

On the other hand, the temperatures range in which is less than, Si can reduce MgO to Mg.

The temperature at which Δ_fG curves of these two substances intersect is 1966 K. Thus, at temperatures less than 1966 K, Mg can reduce SiO₂ and above 1966 K, Si can reduce MgO.

Q. Is it true that under certain conditions

M g

can reduce

A l_{2} O_{3}

and

A l

can reduce

? What are those conditions?

Q. Assertion :

M g O

is reduced by

S i

whereas

S i O_{2}

can be reduced by

M g

Reason:

S i

reduces

M g O

at high temperature

M g

is more electropositive than

S i

and thus reduces

S i O_{2}

Q. Predict conditions under which

A l

might be expected to reduce

M g O

Predict condition under which Al might be expected to reduce MgO.

You are given an Ellingham diagram (deliberately not shown). It is given that for almost all practically achievable temperatures, the $F e \to F e_{2} O_{3}$ line lies above the $A l \to A l_{2} O_{3}$ line and $Δ_{f} G^{\circ}$ for both $A l_{2} O_{3}$ and $F e_{2} O_{3}$ are negative. Which of the following statements is/are true?
