Chemistry · EQUILIBRIUM

हिन्दी

Given below are two statements: Statement I: If a reaction has an extremely large equilibrium constant (\( K_c \gg 10^3 \)), it means that the reactants predominate over products at equilibrium. Statement II: For an ideal gas mixture, partial pressure \( p \) of a gas is directly proportional to its molar concentration at a constant temperature. In the light of the above statements, choose the most appropriate answer from the options given below:

  1. Both Statement I and Statement II are correct.
  2. Both Statement I and Statement II are incorrect.
  3. Statement I is correct but Statement II is incorrect.
  4. Statement I is incorrect but Statement II is correct.

Correct answer · Option 4

Statement I is incorrect but Statement II is correct.

Explanation

Large \( K_c \) implies products predominate nearly to completion, making Statement I false. Statement II is correct from \( p = (n/V)RT = cRT \).
