    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
