What does a particular point on a line of a phase diagram represent ?
VladimirAG [237]

A typical phase diagram has pressure on the y-axis and temperature on the x-axis. As we cross the lines or curves on the phase diagram, a phase change occurs. In addition, two states of the substance coexist in equilibrium on the lines or curves.Jun 6, 2016

The following properties are either physical or chemical. Which one is different from the rest based on those two categories?
wel
Chemical properties can only be analyzed by putting the substance through a chemical reaction, such as combustion.
Physical properties can be analyzed without altering the substance chemically. With that in mind:

Boiling point: physical
Density: physical
Ductility: physical
Heat of combustion: chemical

What is the boiling point of water when the atmospheric pressure exerted on the water is 81 kPa ?
stellarik [79]

Answer: The boiling point of water at 81 kPa will be 298.17 K.

Explanation:

The boiling point of water is 373 K at atmospheric pressure. So, to calculate the boiling point at 81 kPa, we use the law given by Gay-Lussac.

Gay-Lussac Law states that pressure is directly proportional to the temperature when volume and moles remain constant.

Mathematically,

\frac{P_1}{T_1}=\frac{P_2}{T_2

where,

P_1\text{ and }T_1 = Initial pressure and temperature

P_2\text{ and }T_2 = Final pressure and temperature

We are given:

P_1=1atm=101.325kPa\\T_1=373K\\P_2=81kPa\\T_2=?K

Putting values in above equation, we get:

\frac{101.325kPa}{373K}=\frac{81kPa}{T_2}\\\\T_2=298.17K

Hence, the boiling point of water at 81 kPa will be 298.17 K.

An equilibrium mixture contains 0.750 mol of each of the products (carbon dioxide and hydrogen gas) and 0.200 mol of each of the
sasho [114]

1.302  moles of carbon dioxide would have to be added

<h3>Further explanation</h3>

The equilibrium constant is the value of the product in the equilibrium state of the substance in the right (product) divided by the substance in the left (reactant) with the exponents of each reaction coefficient

The equilibrium constant is based on the concentration (Kc) in a reaction

pA + qB -----> mC + nD

\large {\boxed {\bold {Kc ~ = ~ \frac {[C] ^ m [D] ^ n} {[A] ^ p [B] ^ q}}}}

While the equilibrium constant is based on partial pressure

\large {\boxed {\bold {Kp ~ = ~ \frac {[pC] ^ m [pD] ^ n} {[pA] ^ p [pB] ^ q}}}}

The value of Kp and Kc can be linked to the formula '

\large {\boxed {\bold {Kp ~ = ~ Kc. (R.T) ^ {\Delta n}}}}

R = gas constant = 0.0821 L.atm / mol.K

=n = number of product coefficients-number of reactant coefficients

An equilibrium mixture: 0.750 moles of CO2 and H2, and 0.200 moles of CO and H2O

  • We determine Kc (constant concentration)

\displaystyle Kc=\frac{0.75.0.75}{0.2.0.2}\\\\Kc=14.1

  • the amount of carbon monoxide to 0.300 mol

Reaction :

                CO +H₂O ⇔ CO₂ + H₂

initially      0.2   0.2       0.75+x  0.75

reaction    0.1    0.1        0.1         0.1

product     0.3   0.3       0.65+x    0.65

\displaystyle Kc=\frac{(0.650+x)(0.65)}{0.3.0.3}\\\\14.1(0.09)=0.4225+0.65x\\\\1.269-0.4225=0.65x\\\\0.8465=0.65x\\\\x=1.302
