The plot shows the variation of

-\ln \boldsymbol{K}_{\boldsymbol{p}}

versus temperature for the two reactions.

M(s)+\frac{1}{2} O_{2}(g) \rightarrow M O(s)

and

C(s)+\frac{1}{2} O_{2}(g) \rightarrow C O(s)

Identify the correct statement?

becomes zero for the reaction,

\frac{2}{3} A l_{2} O_{3}+2 M g \rightarrow+\frac{4}{3} A l

Below this point, magnesium can reduce alumina. Although thermodynamically feasible, Al is not used for reduction of

Frequently asked questions

What makes a Delta G° (Standard Gibbs energy change) and equilibrium constant question "important" for JEE?

Important questions test core concepts that appear frequently across JEE Main and Advanced papers — definitions, standard formulas, and classic problem types.

Which subtopics in Chemical Thermodynamics are high-weightage?

Key areas include Delta G° (Standard Gibbs energy change) and equilibrium constant. Prioritise these before moving to edge cases.

How many important questions should I revise?

Revise 30–50 important MCQs per unit in the last month before JEE. Focus on questions you got wrong at least once.

Can I practise only important questions on Goodmarks?
