Question
Define vapor pressure and relate it to IMF strength.
A) The vapor pressure is the pressure of the gas that forms above the liquid as the liquid changes phase. Since the liquid must change phase, strong IMFs lead to more gas being able to be formed at a certain temperature which results in higher vapor pressures
B) The vapor pressure is the pressure of the gas that forms above the liquid as the liquid changes phase. Since the liquid must change phase, weak IMFs lead to more gas being able to be formed at a certain temperature which results in higher vapor pressures
C) The vapor pressure is the pressure of the gas that forms above the liquid as the liquid changes phase. Since the liquid must change phase, strong IMFs lead to more gas being able to be formed at a certain temperature which results in lower vapor pressures
D) The vapor pressure is the pressure of the gas that forms above the liquid as the liquid changes phase. Since the liquid must change phase, weak IMFs lead to more gas being able to be formed at a certain temperature which results in lower vapor pressures
Explanation / Answer
The correct answer is Option B
The vapor pressure is the pressure of the gas that forms above the liquid as the liquid changes phase. Since the liquid must change phase, weak IMFs lead to more gas being able to be formed at a certain temperature which results in higher vapor pressures
Reason: The increase in vapor pressure means more amount of gas is produced, the intermolecular forces in the gas are weak because they are far apart from each other and this leads to result in high vapor pressures
