Based on the given van der Waals constants, arrange these hypothetical gases in order of decreasing strength of intermolecular forces. Assume that the gases have similar molar masses. Rank from strongest to weakest intermolecular attraction. To rank items as equivalent, overlap them.

Gas a (L2?atm/mol2) b (L/mol)
Q 5.46 0.0305
D 4.16 0.0373
M 2.25 0.0428
R 1.34 0.0322

What is the vapor pressure of a solution with a benzene to octane?

Use the half-reactions of the reaction au(oh)3 + hi -> au +i2 +h2o to answer the questions

Achemist at a pharmaceutical company is measuring equilibrium constants for reactions in which drug candidate molecules bind to a protein involved in cancer. the drug molecules bind the protein in a 1: 1 ratio to form a drug-protein complex. the protein concentration in aqueous solution at 25 ˚c is 1.74 x10-6 m . drug a is introduced into the protein solution at an initial concentration of 2.00 x10-6m. drug b is introduced into a separate, identical protein solution at an initial concentration of 2.00 x10-6m. at equilibrium, the drug a-protein solution has an a-protein complex concentration of 1.00 x10-6m, and the drug b solution has a b-protein complex concentration of 1.40 x10-6m. a. calculate the kc value for the a-protein binding reaction. b. calculate the kc value for the b-protein binding reaction. c. assuming that the drug that binds more strongly will be more effective, which drug is the better choice for further research?
