Chemical Kinetics Flashcards
1
Q
change in Gibbs free energy (∆G)
A
determines whether or not a reactions is spontaneous
2
Q
chemical mechanisms
A
propose a series of steps that make up the overall reaction
3
Q
intermediates
A
molecules that exist within the course of a reaction but are neither reactants nor products overall
4
Q
rate-determining step
A
slowest step; limits the maximum rate at which the reaction can proceed
5
Q
collision theory
A
states that a reaction rate is proportional to the # of effective collisions between the reacting molecules
6
Q
activation energy
A
exceeded if molecules in proper orientation and have sufficient kinetic energy; for a collision to be effective
