Homework Help Overview

The discussion revolves around the potential energy (PE) of the activated complex in comparison to that of the reactants, within the context of chemical reactions and activation energy.

Discussion Character

  • Conceptual clarification, Assumption checking, Mixed

Approaches and Questions Raised

  • Participants explore the implications of the term 'activate' and its relation to stability and potential energy. Some express views on the energy requirements for the activated complex and its implications for reaction types (exothermic vs. endothermic).

Discussion Status

There are varying interpretations regarding the relationship between activation energy and potential energy of reactants and products. Some participants have offered insights into the stability of the activated complex and its energy requirements, while others challenge these views, indicating a lack of consensus.

Contextual Notes

Participants are navigating assumptions about activation energy and its role in reaction spontaneity, with some expressing confusion over the definitions and relationships involved.

anyone know~~~ ><
pleasez~~~ thankyou in advance! :wink:

What do you think ? What does the verb 'activate' suggest to you ?

Also, what do you know about the stability of an activated complex, and how is stability related to PE ?
 
the PE is higher than the reactants. The activated complex needs more energy in order to be 'activated'.
 
more activation energy yields an exothermic reaction while the less act. energy gives you the endothermic reaction.
 
1+1=1, I think u mean the more potential energy in the reactants than in the products yields an exothermic reaction and vice versa. Activation energy is always more than potential energy of reactants. If it wasnt, the reaction would just go on spontainouesly and never stop.

Not true. Thermicity has nothing to do with Activation Energy.
