QUESTIONS AND ANSWERS. 2024/2025 UPDATE


1 . what is reaction rate? the speed at which
chemical reaction occu
the change in amounts
reactant or produ
produced over time
2. what 2 criteria must be satisfied for a 1 . correct orientation
reaction to be successful? reactants (collis
geometry) 2. collision m
contain enough energy
allow bonding to change
3. what is activation energy? the minimum amount
energy required for
successful reaction
4. T or F increases the temperature of the reac- True, because the hotter
tants increases the reaction rate? molecules are the faster t
move which means they
each other more
5. what is an activated complex? when both reacti
molecules are for
together into a single enti
6. from the
