The vapor pressure of liquid acetone, CH3COCH3, is 40.0 mm Hg at 264 K. A sample of CH;COCH3 is placed in a closed, evacuated container of constant volume at a temperature of 405 K. It is found that all of the CH3COCH3 is in the vapor phase and that the pressure is 50.0 mm Hg. If the temperature in the container is reduced to 264 K, which of the following statements are correct?
States of Matter
The substance that constitutes everything in the universe is known as matter. Matter comprises atoms which in turn are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction, namely solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
Chemical Reactions and Equations
When a chemical species is transformed into another chemical species it is said to have undergone a chemical reaction. It consists of breaking existing bonds and forming new bonds by changing the position of electrons. These reactions are best explained using a chemical equation.
Given:
The vapor pressure of the liquid acetone, CH3COCH3 is 40.0 mm Hg at 264 K.
