Phase equilibrium and solutions Answers to worked examples WE 17.1 Using a phase diagram (on p. 772 in Chemistry3) The normal melting and boiling points for methanol (CH 3 OH) are 175.7 K and 337.8 K, respectively. An increase in volume will move the equilibrium to the side of the gas phase with more particles. Entire chapter is broken down in points and definitions so it gets easy to read and understand. A phase diagram is a map that indicates which phases are present when substances are in equilibrium with the surrounding environment [1,2,3,4,5].An equilibrium state is achieved for the combination of phases that have the minimum total free energy, that is, the most stable system in the environment of interest. The side with fewer gas-phase particles will benefit from a reduction in volume. Enter the email address you signed up with and we'll email you a reset link. In a reversible chemical reaction at equilibrium, if the concentration of any one of the reactants is doubled, then the equilibrium constant will. For each of the following denitions of the system, give the sign (positive, negative, or zero) They are bivariant.
