Here, we are required to determine which parameter change could have cause the shift in molar volume.
The answer is choice D: The temperature increasing by a factor of 2.
The molar volume is the volume occupied by one mole of a gas at standard temperature and pressure.
Since, the volume, temperature and pressure of an ideal gas are related by the ideal gas equation as follow;
P × V = n × R × T
where;
- P = Pressure
- V = volume (molar volume)
- n = no. of moles of the gas
- R = Gas constant
- T = Temperature
From the ideal gas equation, it is evident that the Molar volume is directly proportional to the Temperature of the gas. --Charle's law
Consequently, an increase in the molar volume signifies an increase in the Temperature of the gas provided the pressure and all other parameters remain constant.
Therefore, the parameter that could have caused the molar volume of a gas to increase by a factor of two is;
The temperature increasing by a factor of 2.
