Q27 / 160 · AP EAMCET 2024 (22 May Shift 2) · Chemistry

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
  • Correct answer
    C
    Statement I is correct, but statement II is not correct
  • D
    Statement I is not correct, but statement II is correct

Solution

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.

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