CHEM 102 Lecture 6: Week 6
Document Summary
Systems attempt to restore equilibrium after a disturbance. Shifts away from excess and towards shortage. More reactants=qk (shifts to left away from products) For exothermic reactions, you can add energy produced as a product (and vice versa for endothermic) System compensating by converting the side with more moles of gas to the other side (if there is a difference in the moles of gas) Can increase total pressure by adding an inert gas. No change in equilibrium because the partial pressures remain the same. Adding a catalyst does not change k (changes q) (helps reach (cid:1831)faster) Solution: a mixture of two or more components. Nonpolar substances are soluble in other nonpolar substances. Polar substances are soluble in other polar substances. Not a property of an individual component. Ex. methanol is miscible in water but not in all liquids. Substances with similar intermolecular forces (type and magnitude) are soluble.
