Which set of elements has the MOST similar physical and chemical properties?

When the vapor pressure of water is 0.106 mmHg, determine the reaction quotient for that above equilibrium.

TEA [102]

Answer:

Answer is explained in the explanation section below.

Explanation:

Note: This question is not complete and lacks necessary data to solve. However, I have found a similar question and I will be using its data to solve this question for the sake of understanding and concept.

Solution:

Equilibrium Reaction:

CaO(s) + H2O(g) -->Ca(OH)2(s)

We need to find the reaction quotient for this question:

Q = $\frac{1}{P_{H20} }$

Here, only the pressure of the gaseous reactant will be used and here H20 is the only reactant which is gaseous.

And we are given that, vapor pressure of water is = 0.106 mmHg

So,

Now, we need to convert it into atm

so, 1atm = 760 mmHg

0.106 mmHg = 0.106/760 atm

0.106 mmHg = 1.394 x $10^{-4}$ atm

Plugging in the values in the equation, we get:

Q = $\frac{1}{P_{H20} }$

Q = $\frac{1}{1.394 . 10^{-4} }$

Q = 7173.60 $atm^{-1}$

Yuri [45]

Answer:

43.1atm is the pressure using gas law and 27.2atm using Van der Waals Law.

Explanation:

Ideal gas law is:

PV = nRT

Where P is pressure in atm

V is volume = 4.00L

n are moles of the gas (For chlorine Molar Mass: 70.90g/mol):

500g * (1mol / 70.90g) = 7.052 moles

R is gas constant = 0.082atmL/molK

T is absolute temperature = 25°C + 273 = 298K

To solve the pressure, P:

P = nRT/V

P = 7.052mol*0.082atmL/molK*298K / 4.00L

P = 43.1atm is the pressure using gas law.

Van der Waals equation is:

$P + a(\frac{n}{V})^2 * (V-nb) = nRT$

Where a is 6.58L²atm*mol⁻²

b = 0.056Lmol⁻²

Solving for pressure:

$P + a(\frac{n}{V})^2 = \frac{nRT}{(V-nb)}$

$P = \frac{nRT}{(V-nb)}-a(\frac{n}{V})^2$

$P = \frac{7.052mol*0.082atmL/molK*298K}{(4.00L-7.052mol*0.056L*mol)}-6.58L^2mol^{-2}(\frac{7.052mol}{4.00L})^2$

P = 172.323 / 3.6051 - 20.4866

P = 27.2atm using Van der Waals Law
