Boiling Point of Carbon Disulfide and Vapour Pressure
What is the normal boiling point of carbon disulfide?
The liquid form of carbon disulfide has a boiling point of 46 °C. What is the carbon disulfide vapour pressure in ATM at its typical boiling point?
Answer:
At 35 °C, carbon disulfide has a vapour pressure of 0.700 atm. To calculate the vapour pressure at its boiling point, we can use the modified Clausius-Clapeyron equation. Boiling point occurs when the vapour pressure reaches 1.00 atm.
The normal boiling point of a substance, such as carbon disulfide, is the temperature at which it changes from a liquid phase to a gas phase. In the case of carbon disulfide, it has a boiling point of 46 °C.
At 35 °C, carbon disulfide has a vapour pressure of 0.700 atm. This means that at its boiling point, the vapour pressure will reach 1.00 atm. To calculate the vapour pressure at different temperatures, the modified Clausius-Clapeyron equation can be used along with the temperatures in Kelvin.
Understanding the boiling point and vapour pressure of substances is important in various fields of science and industry. It helps in determining the physical properties and behaviors of different materials.
