Document Summary
Lecture 11: friday jan 27 midterm cutoff. Change in g gives direction of reaction. Note: may be thermodynamically favoured but not instantaneous. Does not tell how many steps it took. Mc with enough e to go forward and reverse. Mc with enough e to go over bump one way. Explains why not all exergonic reaction can occur (ie. diamond to. Determines rate of transformation: correct orientation, collide with enough e. Increase temp (more e to go over ea) 2: use catalyst (alternative mech/pathway decrease ea) (aka increase. Reaction occurs in a single step and passes through a single transition state. Many elementary reaction steps can make an overall reaction. Describes overall reaction without detail about individual elementary reaction steps. Number of reactant molecular entities that are involved in an elementary. Reaction: elementary unimolecular, elementary bimolecular, elementary termolecular (rare because successful orientation. Because b will decrease more we need to make rate equal.
