4
Q
Activation energy?
A
The minimum amount of energy 🔋 required before a collision 💥 will result in a reaction
5
Q
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 old bonds than is released when making the new bonds
7
Q
In terms of bond breaking and making, what is an endothermic reaction?
A
More energy is required to break the old bonds than is released when making the new bonds
