(a)
Interpretation:
By using Le Chatelier’s principle, the effect of the given changes on the extent of hydrolysis of sodium nitrite solution has to be explained.
Concept Information:
The equilibrium, the reactant are forming products at the same rate at which the products are being converted back to reactant, therefore concentration of species are constant.
Le Châtelier’s principle: When system is in equilibrium and stress is added to the system, the system will shift in order to alleviate itself of the stress in order to return to equilibrium.
A change/stress is then made to system at equilibrium.
- 1. Change in concentration, 2. Change in volume, 3. Change in pressure, 4. Change in temperature and 5. Add Catalyst.
(b)
Interpretation:
By using Le Chatelier’s principle, the effect of the given changes has to be explained.
Concept Information:
Chemical Equilibrium: When the forward rate of reaction equals the reverse rate and the concentration of all the species in the system are constant.
The equilibrium, the reactant are forming products at the same rate at which the products are being converted back to reactant, therefore concentration of species are constant.

Note for advanced students: by significant, we mean that the rate of elimination would be greater than the rate of competing substitution reactions. yes O no If you said elimination would take place, draw the major products in the upper drawing area. If you said elimination would take place, also draw the complete mechanism for one of the major products in the lower drawing area. If there is more than one major product, you may draw the mechanism that leads to any of them. Major Products:arrow_forwardDraw one product of an elimination reaction between the molecules below.
