AP EAMCET · Chemistry · Thermodynamics (C)
Two statements are given below.
Statement I: The reaction \(\mathrm{Cr}_2 \mathrm{O}_3+2 \mathrm{Al} \rightarrow \mathrm{Al}_2 \mathrm{O}_3+2 \mathrm{Cr}\) \(\left(\Delta G^{\ominus}=-421 \mathrm{~kJ}\right)\) is thermodynamically feasible
Statement II: The above reaction occurs at room temperature.
The correct answer is
- A Both the statements I \& II are correct
- B Both the statements I \& II are not correct
- C Statement I is correct, but statement II is not correct
- D Statement I is not correct, but statement II is correct
Answer & Solution
Correct Answer
(C) Statement I is correct, but statement II is not correct
Step-by-step Solution
Detailed explanation
Certain amount of activation energy is essential ever for such reactions which are thermodynamically feasible therefore heating is required. So statement I is correct but II is incorrect.
