Question

What fraction of molecule in H-gas have a - kinetie enengy within. KE = ±10% of KE at 25°C and 500 °C ? What fraction of molecules in mercury vapour have the above range of Kinetic enengy at 25°c?​

Answer 1

What fraction of molecule in H-gas have a - kinetie enengy within. KE = ±10% of KE at 25°C and 500 °C ? What fraction of molecules in mercury vapour have the above range of Kinetic enengy at 25°c?

Mean K.E = 3KE/2

10/1000 = 3K×500/2

3K = 20/5×10⁴

Molecule in H-gas have a - kinetie enengy within. KE = ±10% of KE at 25°C and 500 °C .

Fraction of molecules in mercury vapour have the above range of Kinetic enengy at 25°c = 50×60-⁴ Jule .
