Consider the equilibrium reaction. 2 A + B − ⇀ ↽ − 4 C After multiplying the reaction by a factor of 2, what is the new equilibr

vredina [299]

Answer : The correct expression for equilibrium constant will be:

$K_c=\frac{[C]^8}{[A]^4[B]^2}$

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,

$4A+2B\rightleftharpoons 8C$

The expression of $K_c$ will be,

$K_c=\frac{[C]^8}{[A]^4[B]^2}$

Therefore, the correct expression for equilibrium constant will be, $K_c=\frac{[C]^8}{[A]^4[B]^2}$

What has to be true about available resources for competition to exist?

Mila [183]

Answer:

Limited

Explanation:

For competition to exist within a population or between population, shared or common resources that organisms holds very important must be very limited and scared.

Competition is a struggle between organisms for limited resources in the ecosystem.

It is an interaction between organisms in which one of them is harmed.
Competition originates from limited supply of shared or mutual resources among organisms.
When competition is between organisms from different population, it is called an interspecific competition.
Competition between organisms within the same population, i.e of the same species is intraspecific competition.
