Answer:

0.00227 atm is the pressure of B(g)at equilibrium.

Explanation:

2A(g)\rightleftharpoons B(g)

The value of equilibrium constant = K_p=7.80\times 10^{-5}

Partial pressure of A before heating = 5.40 atm

2A(g)\rightleftharpoons B(g)

Initially

5.40 atm         0

at equilibrium

(5.40-2p)atm       p

The expression of an equilibrium constant can be given as

K_p=\frac{p}{(5.40-2p)^2}

7.80\times 10^{-5}=\frac{p}{(5.40-2p)^2}

Solving for p ;

p = 0.00227 atm

Partial pressure of B at 500 K = 0.00227 atm

0.00227 atm is the pressure of B(g)at equilibrium.

If 20.0 mL of a 0.0800 M HNO3, 35.0 mL of a 0.0800 M KSCN, and 40.0 mL of a 0.0800 M Fe(NO3)3 are combined, what is the initial
Tems11 [23]

Answer:

0.0295M

Explanation:

As you can see, in the mixture you have KSCN and other compounds. The KSCN in solution is dissolved in K⁺ ions and SCN⁻ ions. That means initial concentration of SCN⁻ ions is the same of KSCN, 0.0800M.

You are adding 35.0mL of this solution and the total volume of the mixture is 20.0mL + 35.0mL + 40.0mL = 95.0mL.

That means you are diluting your solution 95.0mL / 35.0mL = 2.714 times.

And the concentration of SCN⁻ is:

0.0800M / 2.714 =

<h3>0.0295M </h3>
