The equilibrium-constant expression for a reaction written in one direction is the __________ of the one for the reaction writte

VLD [36.1K]

Answer:

reciprocal

Explanation:

The equilibrium constant for an equilibrium reaction is the ratio of the equilibrium constant for the forward reaction, Kf, to the equilibrium constant for the reverse reaction, Kr:

For A ⇄ B

The forward reaction is: A → B, with rate constant is Kf = K₁ and
The reverse reaction is: B → A, with rate constant Kr = K₂

$K_{eq}=\dfrac{K_f}{K_r}=\dfrac{K_1}{K_2}$

When you write the reaction in the other reaction, the forward and the reverse reaction are exchanged:

For B ⇄ A

The forward reaction is B → A, with rate constant Kf = K₂
The reverse reaction is A → B, with rate constant Kr = K₁

$K'_{eq}=\dfrac{K_f}{K_r}=\dfrac{K_2}{K_1}$

As you see:

$K'_{eq}=\dfrac{1}{K_{eq}}$

Thus, the equilibrium-constant expression for a reaction written in one direction is the  reciprocal___ of the one for the reaction written for the reverse direction.

How many grams of NaCl is needed to make 750mL of a 2.4 M NaCl solution?

Aleksandr [31]

Answer:

Molarity of the solution = 3.000 M

Volume of the solution = 250.0 mL = 0.25 L

moles in 250.0 mL = molarity x volume of the solution

= 3.000 M x 0.25 L

= 0.75 mol

Hence, 0.75 mol of NaCl is needed to prepare 250.0 mL of 3.000 M NaCl solution.

Moles (mol) = mass (g) / molar mass (g/mol)

Moles of NaCl in 250.0 mL = 0.75 mol

Molar mass of NaCl = 58.44 g/mol

Mass of NaCl in 250.0 mL = Moles x Molar mass

= 0.75 mol x 58.44 g/mol

= 43.83 g

Hence, 43.83 g of NaCl is needed to prepare 250.0 mL of 3.000 M solution.

when a species must survive changes in the environment, would they want to use sexual or asexual reproduction. Explain

eduard

Sexual. First of all because any thing that is something like an animal can not participate in asexual reproduction. A species is a small population of a certain animal that can survive and produce fertile offspring
