Which of the following is true for the equilibrium constant of a reaction?

Chemistry
1 answer:
CaHeK987 [17]2 years ago
4 0

Answer:

The correct answer is <em>It is a ratio of the concentrations in a reaction.</em>

Explanation:

⇒ It is a ratio of the concentrations in a reaction.

This sentence is true because the equilibrium constant is calculated from the product of the concentration of the reaction products divided into the product of the concentrations of the reactants, each concentration raised by the stoichiometric coefficient. For example, for the following reaction:

aA + bB → cC + dD

The equilibrium constant is expressed as:

K = \frac{[C]^{c}[D]^{d}  }{[A]^{a} [B]^{b} }

⇒ It remains the same at different temperatures.

The sentence is false because the equilibrium constant changes with the temperature. In general, an endothermic reaction is favored by the increment of temperature (the equilibrium shifts to the right side) and disfavored with the decrease in temperature (shifts to the left).

⇒ It is represented by the symbol H.

This sentence is false because the equilibrium constant is represented with the letter K.

⇒ Its value is always close to 1.

It is not true because the equilibrium constant can be a number below or above 1.

K < 1 ⇒ there is more concentration of reactants at equilibrium

K > 1 ⇒ there is more concentration of products at equilibrium

Answer:

Osmosis

Explanation:

Water is very essential for the body. When we drink water, our blood cells absorbs water from the body. This happen by a process called as osmosis process. Osmosis is type of diffusion process.

Water along with oxygen and carbon dioxide are some of the simple molecules that moves into the blood cell. Osmosis is the process by which water molecules passes into the cell bodies through its semi permeable membrane.
