Answer:

$Kp_2} =2.0$

Explanation:

$K_{p1}= 1.8$

$K_{p2}= ???$

$T_1= 298K$

$T_2 = 415 K$

$\delta H$ = 0.64 kJ/mol = 640 J/mol

R = 8.314 J/mol.K

Using Van't Hoff Equation:

$In (\frac{Kp_2}{Kp_1} )=(-\frac{DH}{R} *(\frac{1}{T_2}-\frac{1}{T_1} )$

$In (\frac{Kp_2}{1.8} )=(-\frac{640}{8.314} *(\frac{1}{415}-\frac{1}{298} )$

$In (\frac{Kp_2}{1.8} )=0.072827$

$(\frac{Kp_2}{1.8} )= e^{0.0728727}$

$\frac{Kp_2}{1.8} =1.075593605$

$Kp_2} =1.075593605*1.8$

$Kp_2} =1.936068489$

$Kp_2} =2.0$

Using the periodic table to locate each element, write the electron configuration of(c) Re.

Aleksandr [31]

Rhenium is a chemical element with the symbol Re and atomic number 75. The electron configuration of Re is [Xe] $6s^{2} 4f^{14} 5d^{5}$ .

<h3>How to write an electronic configuration?</h3>

1. Identify the given element and its atomic number from the periodic table.

2. Write the electron configuration by the energy level and the type of orbital first, then the number of electrons present in the orbital as superscript.

The easiest way to write the electronic configuration for any element is by using a diagonal rule for electron filling order in the different subshells according to the Aufbau principle.

The 3 rules for writing the electron configuration in the orbital box diagram are – the Aufbau rule, the Pauli-exclusion rule, and Hund's Rule.
