GEN CHEM CH 9-SOLUTIONS
Terms in this set (15)
Substances that combine together to form a single phase are known as?
Gasses "dissolved" into other gases can be thought of as solutions, but are more properly defined as?
mixtures, bc according to kinetic molecular theory of gases, their molecules do no interact at all that much chemically
When considering a solution, containing solute and solvent, which remains in the same phase after mixing?
Electrostatic interaction b/w solute and solvent molecules
Solvation is also known as d_______?
When the new interactions formed after solvation are stronger than the original ones, this is considered an ? process and is favored @ _____ temps?
When the new interactions formed after solvation are weaker than the original ones, this is considered an endothermic process and is favored at ____ temps?
Proteins dissolve in solution with their most hydrophilic amino acids on the outside and hydrophobic amino acids on the inside bc this maximizes the increase in ? during dissolution?
When the strength of the new interaction(s) formed after solvation are equal to the overall strength of the original interactions, overall the enthalpy change for the dissolution is = to ?
When delta H=0 for a dissolution, the solution is known as an?
At constant temp and pressure, entropy always ? upon dissolution?
As with any process, the spontaneity of dissolution depends on the change in?
Gibbs free energy
Spontaneous processes are associated with a ? in free energy?
Non spontaneous rxns are associated with an increase in?
The degree to which energy is dispersed throughout a system or the amount of energy distributed from the system to the surroundeing
