QUESTION:
(b) Calculate the rms speed of NF3 molecules at 25 C.
ANSWER:Problem 10.83b(b) Calculate the rms speed of NF3 molecules at 25 °C. Step-by-step solution Step 1 of 2 (b) The expression for root mean square speed is: u = 3RT s MHere, M is the molar mass of particle (N3 ) = 71.01 g/mol -3= 71.01 x 10 kg/molR, gas constant = 8.314 J/mol-K 2 2= 8.314 J/mol-K x 1 kgm /s 1J= 8.314 kg-m /s -mol-KT, absolute temperature = 25°C= (25 + 273) K= 298 K
