Energy must be transferred into or out of a system in order to cause phase change.In addition changes in the energy can be directly related to pressure volume changes.If equal moles of each gas is compressed which one would have the largest pressure volume change during condensation? Heat of vaporization also given as
NaF(29.3kj/mol)
HCl(1.99KJ/mol
O2(0.45KJ/mol
CHCL3(9.20KJ/mol
To determine which gas would have the largest pressure-volume change during condensation, you need to compare the heat of vaporization of each gas. The greater the heat of vaporization, the more energy is required to change the gas from a vapor to a liquid state.
The heat of vaporization is the amount of energy needed to convert one mole of a substance from a liquid to a gas at a constant temperature and pressure. The higher the heat of vaporization, the more energy is required to vaporize the substance.
By comparing the heat of vaporization values provided for NaF, HCl, O2, and CHCl3, you can identify the gas with the highest value, indicating the largest pressure-volume change during condensation.
NaF (29.3 kJ/mol)
HCl (1.99 kJ/mol)
O2 (0.45 kJ/mol)
CHCl3 (9.20 kJ/mol)
From the given values, NaF has the highest heat of vaporization at 29.3 kJ/mol. This means that NaF requires the most energy to change from a liquid to a gas, indicating that it would have the largest pressure-volume change during condensation.
Therefore, NaF would have the largest pressure-volume change among the gases when equal moles of each gas are compressed.
