Concept Introduction:
Le Chatelier’s principle: If an equilibrium is disturbed by changing conditions, the system will moves the equilibrium to reverse the change.
Factor’s that effect chemical equilibria:
- Concentration – Equilibrium will be affected by changing the concentration of reactant or product. If we increase the concentration of reactant system will try to reverse the change by favoring forward reaction and thus increase the concentration of products. Likewise adding products increase yield of reactants.
- Temperature – When the temperature increases equilibrium will shift in the endothermic direction, in the direction that absorbs heat. When the temperature decreases equilibrium will shift in the exothermic direction, in the direction that releases heat.
- Pressure – If the reaction consists of only liquid and solid reactants and products, pressure has no effect in the equilibrium.
In gas reactions if the number of moles has no change then there will be no effect by pressure on equilibrium.
If pressure increases then equilibrium will shift to the direction having less number of molecules and if pressure decreases system will shift to the direction having more number of molecules.

Factor’s that effect chemical equilibria:
- Concentration – Equilibrium will be affected by changing the concentration of reactant or product. If we increase the concentration of reactant system will try to reverse the change by favouring forward reaction and thus increase the concentration of products. Likewise adding products increase yield of reactants.
- Temperature – When the temperature increases equilibrium will shift in the endothermic direction, in the direction that absorbs heat. When the temperature decreases equilibrium will shift in the exothermic direction, in the direction that releases heat.

- In a study of O2 uptake by muscle at high altitude, a physiologist prepares an atmosphere consisting of 79 mole % N2, 17 mole % 16O2, and 4.0 mole % 18O2. (The isotope 18O will be measured to determine O2 uptake.) The total pressure is 0.75 atm to simulate high altitude. Calculate the mole fraction and partial pressure of 18O2 in the mixture.arrow_forwardO E-If answers (1), (2), (3) and (4) are TRUE Which of the following is NOT true about the liver lobule? * (1) Bile canaliculi transport bile towards the bile ducts located at the corners of the liver lobule. (2) Sinusoidal capillaries drain into the central vein. (3) Liver lobules are capable of producing plasma proteins such as albumin.

Oxygen binds irreversibly to this molecule.2. This molecule has greater affinity for oxygen.3. The oxygen dissociation curve is sigmoidal in shape.4. Carbon monoxide binds at an allosteric site, lowering oxygen binding affinity.5. The binding pattern for this molecule is considered cooperative.6. This molecule delivers oxygen more efficiently to tissues.7. As oxygen binds to this molecule, the shape of the molecule changes, enhancing further oxygen binding.8. The oxygen dissociation curve is hyperbolic in shape.arrow_forwardWhat happens to pCO2 levels as the disease (Idiopathic pulmonary fibrosis) progresses, and what would the teeter totter look like in this situation?CO2+ H2O ⇌ H2CO3 ⇌ H++ HCO3−arrow_forwarddiscuss the mechanism of the bohr effect that occurs during the interactions of Hb with oxygen under physiological conditions in the lungs and tissues. make use of relavant graphs and diagrams to explain your answer.arrow_forward
