Reactions of Aromatic Compounds - Rutgers University

The formation of the sigma complex is an endothermic and energetically unfavorable process - it is therefore the rate determining step. The second step is exothermic since it regenerates the aromatic system. The overall reaction is exothermic by about -11 kcal/mol (-45kJ/mol).

Reactions of Alcohols - Rutgers University

The first step is the exothermic protonation of the hydroxyl, followed by the slow, endothermic, rate determining ionization to generate the cation. The fast deprotonation is exothermic and produces the alkene. Since the RDS is the formation of the carbocation, the ease of formation dictates the reaction rates of 3° > 2° > 1°.

Interpreting Unexpected Events and Transitions in DSC …

Event 5: Baseline Shift After Endothermic or Exothermic Peaks Causes Baseline shifts are caused by changes in sample weight, heating rate, or the specific heat of the sample. A change in specific heat often occurs after the sample has gone through a transition such as curing, crystallization, or melting. Sample weight often changes

CH301 Worksheet 11 (Answer Key)

endothermic. A negative value for ΔH means that the system is losing heat, and the reaction is exothermic. A positive value for w means that work is being done on the system (the surroundings are doing work on the system). A negative value for w means that work is being done by the system (the system is doing work on the surroundings).
