arrangement of the following gas molecule in their increasing average speed at the same temperature. O2, N2, H2O,CO2,NO2 and Cl2
To determine the arrangement of the gas molecules based on their increasing average speed at the same temperature, you need to consider the relative molar masses and the relationship between molar mass and average speed.
In general, at the same temperature, lighter gas molecules tend to have higher average speeds compared to heavier gas molecules. This is due to the fact that lighter molecules have lower molar masses and therefore experience less intermolecular forces, allowing them to move faster.
Let's examine the molar masses of the given gas molecules:
O2: Molar mass = 32 g/mol
N2: Molar mass = 28 g/mol
H2O: Molar mass = 18 g/mol
CO2: Molar mass = 44 g/mol
NO2: Molar mass = 46 g/mol
Cl2: Molar mass = 71 g/mol
Based on their molar masses, we can expect the arrangement of the molecules in increasing average speed to be:
H2O (18 g/mol) < N2 (28 g/mol) < O2 (32 g/mol) < CO2 (44 g/mol) < NO2 (46 g/mol) < Cl2 (71 g/mol)
Therefore, the arrangement of these gas molecules in increasing average speed at the same temperature is:
H2O < N2 < O2 < CO2 < NO2 < Cl2
