3
Q
What is a reaction profile?
A
diagram showing how the energy changes in a reaction
4
Q
what is the activation energy
A
minimum amount of energy required before a collision will result in a reaction
5
Q
what is bond energy
A
the energy required to break a bond or the energy released when a bond is formed
6
Q
In terms of bond breaking and making, what is an
exothermic reaction?
A
less energy is required to break the bonds than is released when making the bonds
7
Q
In terms of bond breaking and making, what is an
endothermic reaction?
A
more energy is required to break the bonds than is released when making the bonds
