Question

Part B- Calculate the rms speed of CO molecules at 320 K in M/sec

Part C- Calculate the rms speed of Cl2 molecules at 320 K in M/sec

Part D- Calculate the most probable speed of CO molecules at 320 K in M/sec

Part E- Calculate the most probable speed of Cl2 molecules at 320 K in M/sec

Answer 1

Part B

Where R is gas constant

T is the temperature

M is the molar mass of the gas

Given,

T= 320K

Using

R= 8.314 J /K/mol = 8.314 kg m²s^-2K^-1mol^-1 [ 1 Joule= 1 kg m²s^-2]

M (molar mass of CO)= 28g/mol = 0.028 kg/mol

=

= 533.90 m/s

Part c

Molar mass of Cl₂ = 71 g/mol

=0.071 kg/mol

= 335.283 m/s

Part d

    

Molar mass of CO =0.028 kg/mol

= 435.93 m/s

Part e

Molar mass of Cl₂ =0.071 kg/mol

= 273.76 m/s
