Answer:
Explanation:
Equilibrium constant is defined as the ratio of concentration of products to the concentration of reactants each raised to the power their stoichiometric ratios. It is expressed as
The given balanced equilibrium reaction is,
At eqm. conc. 1.85 M 9.26M 0.254M
The expression for equilibrium constant for this reaction will be,
Now put all the given values in this expression, we get :
Thus the value of the equilibrium constant is
Answer:
The ratio of atoms of potassium to atoms of oxygen is 2:1
Explanation:
As the equation given is :
<h3>
</h3>
The product formed is 2 moles of potassium oxide .
Amount of potassium atom in the potassium oxide is 2 atoms of potassium and amount of oxygen atom present here is 1 atom of oxygen .
But we have 2 moles of potassium oxide . So, the potassium and oxygen atoms will be multiplied by 2 .
Hence , we get 4 atoms of potassium and 2 atoms of oxygen .
Ratio of potassium to oxygen atoms is - 4:2
Therefore , 2:1
Answer:
Addition reactions are thermodynamically favored at low temperatures.
Explanation:
Compared to substitutions or eliminations, addition reactions do not require to break as many bonds as them, as such, they do not require such a high input of energy (ie. temperature) in order to take place.
This is why if there's a high temperature, the reactions that require more energy -like substitutions or eliminations- will be more thermodinamically favored than the reactions that require less energy -like additions-, and viceversa.
