Arrange the following molecules in order of increasing average molecular speed. CO2 at 332K, CH4 at 435K, CH4 at 395K, N2 at 395K Enter formulas and temperatures in the boxes below: 1 = slowest, 4 = fastest

Respuesta :

Answer:

1 Slowest = CO2 at 332K

2 N2 at 395K

3 CH4 at 395K

4 fastest = CH4 at 435K

Explanation:

The molecular speed depends on the temperature and molar mass of the molecules

Speed of CO2 at 332K:

 ⇒ Molar mass CO2 = 44.01 g/mole

 ⇒ Temperature = 332 K

332/ 44.01 = 7.544

Speed of CH4 at 435K

 ⇒ Molar mass CH4 = 16.04 g/mole

 ⇒ Temperature = 435K

435/16.04 = 27.12

Speed of CH4 at 395K

⇒ Molar mass CH4 = 16.04 g/mole

 ⇒ Temperature = 395 K

395/16.04 = 24.626

Speed of N2 at 395K

⇒ Molar mass N2 = 28 g/mole

 ⇒ Temperature = 395 K

395/ 28 = 14.11

1 Slowest = CO2 at 332K

2 N2 at 395K

3 CH4 at 395K

4 fastest CH4 at 435K
