The statements correct about the speed of gas particles have been A and B.
The movement of the gas particles has been influenced by the factors such as temperature and molar mass.
The speed of the gas has been inversely proportional to the molar mass. The molecules with higher molar mass will have lesser speed.
The statements that have been based on the speed of gas molecules are:
- The speed of molecules has been based on the molar mass. The particles with the same kinetic energy at the same temperature will be moving at the same speed.
Thus statement A is correct.
- The molar mass of nitrogen has been 28 g/mol, and that of oxygen has been 32 g/mol. Thus, the rate of diffusion of nitrogen has been faster than oxygen because of the lower molecular mass.
Thus statement B is correct.
- The molar mass of Hydrogen has been lower than the molar mass of oxygen. Thereby the speed of effusion of gas has been inversely proportional to the square root of the molar mass. Thus with the hydrogen, the molar mass is lesser thus, the speed has been lower than the oxygen.
Thus statement C is incorrect.
- The kinetic energy of the gas has been based on the molar mass. The higher mass has resulted in lower kinetic energy.
Thus statement D is incorrect.
The statements correct about the speed of gas particles have been A and B.
