Module 13 Flashcards
1
Q
1st Law of Thermodynamics tells us
A
That energy cannot be created or destroyed
2
Q
Change in Enthalpy is
A
The energy change that accompanies a chemical reaction
3
Q
Bond energy is
A
The strength of the chemical bond
4
Q
Hess’s Law states
A
Enthalpy is a state function (final destination, and not the way you get there) and is therefore independent of path
5
Q
Activation energy is
A
The energy necessary to start a chemical reaction
6
Q
Entropy is
A
The measurement of disorder that exists in any system
7
Q
2nd Law of Thermodynamics
A
Every system left to itself will tend toward a condition of minimum potential energy and maximum entropy (disorder)
