Energy Changes in Chemical Reactions
When a system loses enthalpy, the reaction is this.
A chemical in its phase at 25 degrees Celsius and 100 kpa is called this.
What is the standard state?
The degree of disorder or randomness in a chemical system can be considered this.
What is Entropy?
When ΔH > 0, this is that type of reaction.
What is Endothermic?
The heat of formation can be used for this of compounds.
What is comparing the stability?
If there is Low Entropy, ΔS is ___.
What is Below Zero?
Or
What is Negative?
For this type of reaction, ΔH is always negative.
What is a Combustion reaction?
For this, the change of enthalpy in a chemical reaction is independent of the pathway between the inital and final states (at a constant pressure).
What is Hess's Law?
There is more entropy when ice does this.
What is melt?
The measure of the total energy possessed by a substance or a group of substances.
What is Enthalpy?
6CO2 + 6H2O -> C6H12O6 + 6O2 is this reaction.
What is Photosynthesis?
If enthalpy and temperature are positive, while entropy is negative then the change in Gibbs Free Energy is this.
What is Positive?
The amount of heat energy required to change the temperature of a unit of mass of a substance by 1 degree (Celsius/Kelvin).
What is Specific Heat Capacity?
What is Bond Energy?
Setting ΔG to what allows you to find the temperature when the reaction becomes spontaneous.
What is Zero?
