<u>Answer:</u>
<u>For a:</u> The equilibrium mixture contains primarily reactants.
<u>For b:</u> The equilibrium mixture contains primarily products.
<u>Explanation:</u>
There are 3 conditions:
- When
; the reaction is product favored.
- When
; the reaction is reactant favored.
- When
; the reaction is in equilibrium.
For the given chemical reactions:
- <u>For a:</u>
The chemical equation follows:
The expression of for above reaction follows:
As, , the reaction will be favored on the reactant side.
Hence, the equilibrium mixture contains primarily reactants.
- <u>For b:</u>
The chemical equation follows:
The expression of for above reaction follows:
As, , the reaction will be favored on the product side.
Hence, the equilibrium mixture contains primarily products.
