A
Measure of the disorder of the system.
2
Q
Define endothermic.
A

3
Q
On an energy/reaction graph what is the difference between an exo and endothermic graph?
A
The energy of the products is lower than the reactants for exothermic, and higher for endothermic.
4
Q
Define a spontaneous reaction.
A
Once started, will continue without inside intervention.
5
Q
