Chemistry · EQUILIBRIUM

हिन्दी

In the student activity demonstrating dynamic equilibrium using two measuring cylinders (1 and 2) and two glass tubes, what determines the final constant level of liquid in the two cylinders when transfer equilibrium is reached?

  1. The ratio of the internal diameters (cross-sectional areas) of the two transfer tubes.
  2. The ambient atmospheric pressure and room temperature exclusively.
  3. The initial volume of coloured liquid placed in cylinder 2 only.
  4. The total time duration of each individual transfer step.

Correct answer · Option 1

The ratio of the internal diameters (cross-sectional areas) of the two transfer tubes.

Explanation

When tubes of different diameters are used, the volumes transferred per cycle balance only when liquid heights adjust in proportion to the inverse cross-sectional area ratio, showing diameter controls the final relative levels.

Given below are two statements:\n Statement I: Chemical equilibrium can be attained from either direction, whether starting with pure reactants or pure products.\n Statement II: The Law of Chemical Equilibrium and Law of Mass Action was proposed by Cato Maximillian Guldberg and Peter Waage in 1864. \nIn the light of the above statements, choose the most appropriate answer from the options given below:→For a 0.10 M aqueous solution of a diprotic acid \( \text{H}_2\text{X} \), the ionization constants are \( K_{a_1} = 4.0 \times 10^{-5} \) and \( K_{a_2} = 1.6 \times 10^{-11} \). The concentration of divalent anion \( [\text{X}^{2-}] \) at equilibrium is:→When \( \text{HCl} \) gas is passed through a saturated solution of \( \text{NaCl} \), pure \( \text{NaCl} \) precipitates out while impurities like \( \text{MgSO}_4 \) and \( \text{Na}_2\text{SO}_4 \) remain dissolved. The underlying reason for this phenomenon is:→In the equilibrium \( \text{Fe}^{3+}(\text{aq}) + \text{SCN}^-(\text{aq}) \rightleftharpoons [\text{Fe}(\text{SCN})]^{2+}(\text{aq}) \) (deep red), what happens to the red colour intensity upon the addition of oxalic acid \( (\text{H}_2\text{C}_2\text{O}_4) \) and why?→
