Part D Friedel-Crafts Special considerations

Review) Explain why the second reaction in Reaction Sequence I is slower than the first 

Consider a h5 othetical solution consisting of one molecule of benzene, one molecule of 

For Reaction Sequence II in Model 9, if you mix equal amounts of benzene and electrophile (eg. CH3CH2CI + AICI3 catalyst) you obtain mostly the di- and tri-ethyl products shown in Reaction Sequence II and very litde of the mono-ethyl product (ethylbenzene). Explain.
