The given reaction is
2Li₂O₂(s) ⇄ 2Li₂O(s) + O₂(g)
The equilibrium constant for the specified reaction will be because the concentrations of solids and pure liquids are not taken into account in the expression of the equilibrium constant:
K=[O 2 ]
The reaction reaches equilibrium when Li₂O₂ is added at the conclusion of the reaction, ensuring that the amount of O₂ remains constant or unchanged.
What is thermal decomposition?
Thermolysis, also known as thermal decomposition, is a chemical decomposition brought on by heat. The temperature at which a substance decomposes chemically is known as the decomposition temperature of the substance. Since heat is necessary to break the chemical bonds in the substance that is undergoing breakdown, the process is typically endothermic.

Answer:
Dalton law states that the partial pressure of a gas in a mixture of gases is equal to the total pressure of the mixture.
Answer:Inertia is the property of a body to remain at rest or to remain in motion with constant velocity. Some objects have more inertia than others because the inertia of an object is equivalent to its mass.
Explanation:
Periodic trends , arising due to the arrangement of the different elements in a periodic table. It includes electronegativity, ionization energy,electron affinity, atomic radius, metallic character and chemical reactivity.
With the help of the periodic trends,we can predict or determine an element's properties.
Answer:
The final temperature of the solution is 46.93°C
Explanation:
we have to calculate the heat produced.
where,
= enthalpy change = 81.5 kJ/mol
q = heat released = ?
m = mass of CaCl_2 = 15.0 g
Molar mass of CaCl_2 = 110.98 g/mol
Now put all the given values in the above formula, we get:
calculate the final temperature of solution in the calorimeter.
where,
q = heat produced = 11.0 kJ = 11000 J
m = mass of solution = 15.0 + 105 = 120.0 g
c = specific heat capacity of water = 4.18J/g°C
= initial temperature = 25.0°C
= final temperature = ?
Now put all the given values in the above formula, we get:
The final temperature of the solution is 46.93°C
