Deuterium (D or 2H) is an isotope of hydrogen. The molecule D2 undergoes an exchange reaction with ordinary hydrogen, H2, that l
Paladinen [302]

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
