In this exercise, we will investigate the chemical potential μ upon a change in volume. we will use the fact that f=u−ts and μ=∂f∂n. we will compute μ(vf)−μ(vi) in all questions, take n=20 moles (which is 20 times avagodro's number of particles), t=300 k, vi=0.01 m3,vf=0.02 m3 1) for a gas with an excluded volume: u=32nkt+const s=nkln(v−bn)+const if b=10-28 m3, compute μ(vf)−μ(vi)

Asubject in a clinical research trial experiences a serious, unanticipated adverse drug experience. how should the investigator proceed, with respect to the irb, after the discovery of the adverse event occurrence? a. do not report the adverse drug experience to the irb since it is a common adverse experience. b. report the adverse drug experience to the irb only if there are several other occurrences. c. report the adverse drug experience as part of the continuing review report. d. report the adverse drug experience in a timely manner, in keeping with the irb's policies and procedures, using the forms or the mechanism provided by the irb.
