Which can be explained as applications of Le Chatelier's principle?

Options

  1. ATransport of oxygen by haemoglobin in blood
  2. BRemoval of C O 2 from tissues by blood
  3. CTooth decay due to use of sweet substances
  4. DAll of the above

Correct answer

D. All of the above

Step-by-step solution

(i) The haemoglobin of RBC combines with oxygen in lungs following the equilibrium, H b ( s ) + O 2 ( g ) ⇌ H b O 2 ( s ) When these are at lungs, the partial pressure of O 2 being appreciable show forward reaction, however when they pass to tissues, the partial pressure of O 2 decreases to favour backward reaction releasing O 2 . (ii) Removal of C O 2 from blood is based on the equilibrium, C O 2 ( g ) + H 2 O ( l ) ⇌ H + ( a q ) + H C O 3 - ( a q ) In tissues C O 2 gets dissolved in H 2 O due to high pressure whe
