Answer : The correct expression for equilibrium constant will be,
Explanation :
Equilibrium constant : It is defined as the equilibrium constant. It is defined as the ratio of concentration of products to the concentration of reactants.
The equilibrium expression for the reaction is determined by multiplying the concentrations of products and divided by the concentrations of the reactants and each concentration is raised to the power that is equal to the coefficient in the balanced reaction.
As we know that the concentrations of pure solids and liquids are constant that is they do not change. Thus, they are not included in the equilibrium expression.
The given equilibrium reaction is,
The expression of will be,
Therefore, the correct expression for equilibrium constant will be,
Answer:
Volcanoes form when magma from earth's upper mantle moves its way up to the surface. When the magma is all the way up the surface, it erupts and makes lava while at the same time, ash deposits. Once the volcano continues to erupt even more it starts getting bigger and bigger.
