Question

Vessel A contains CO(g) at 0°C and 1 atm. Vessel B contains SO2(g) at 20°C and 0.5 atm. The two vessels have the same volume.

a) Which vessel contains more molecules?

b) Which contains more mass?

c) In which vessel is the average kinetic energy of molecules higher?

d) In which vessel is the rms speed of molecules higher?

(Could you write it out neatly please)

Answer 1

Vessel A contains colo) at o°c vessel B contering Sozig, at 200 and tahmi and a.s atm. So 1 PA zlatm PB 2 0.5ath TA 20°C 2273k , R = 0.0821 Latmand" it TB 22000 2293 K Let VA V gal Liter PAVA 2 MARTA NA PAVA RTA Ixl 273X0.0821 22.4133 = 0.044616366 mole nB = PBVB 00:5X B 0.0821 x 293 0.5 RT 30.02078544 24.0553 mole Since the moleg na no So vessel A have more molecules than vessel B 6 - Mass of vessel A- Molar Mass of CO (9) = 28.01 gimol Molar mass of SO2 (9) = 64.066 g/mol Mass of vessel A = mole of versel A x Molar mass of co 20.044616366 X 28.01 = 1.2497044 gram mass of vessel Ba mole of vessel B x molar mass som = 0'02078544 x 64.066 I 1.33164 gram. So mass of vessel B is greater than vessel A [MALMB]

© » Average Kinetic Energy = Ş QT So More Temperafure more will be average kinetic Energy. temperature of vessel B is higher than versel A. To 7 Те (Average kinetic Energy) > (Average kinetic Energy) A- so 0. Since Vrms = SRT VB a TB MB VA =TA MO VG N TO MA 17490.018 a = 2.13112796 N . 8206.93 - 1.459838 So IVA 21.459038 X VB 1 So VA YUB rms speed of vessel A is higher
