Problem 11.5
Determine the average value of the kinetic energy of the particles of an ideal gas at these temperatures 0°c and 50 °c temperatures ?
Data
K.e per mole =?
T= 0 °C +273=273k
T =50°c+273=323k
K.e=3/2kt
K.e =3/2×1.38×10-²³ × 273
=k.e 5.65×10-²¹ j......

Determine the kinetic energy of per mole of the particles of an ideal gas at 0 and 50°C temperatures?
Solution :
K.e per mole =3/2 rt
K.e per mole =3/2 ×8.31×273
K.e per mole =3402.9 joule/mole
