Spontaneity
The opposite of a spontaneous process.
What is a non-spontaneous process?
The symbol for Enthalpy.
What is H (deltaH)?
The letter that represents Entropy.
What is S?
The movement of heat between two things.
What is heat transfer?
The meaning of G in chemical thermodynamics.
What is Gibbs Free Energy?
The type of reaction that occurs when a process releases energy, often an indicator of a spontaneous process.
What is an exothermic reaction?
What is Enthalpy?
The thing that Entropy measures.
What is the amount of arrangements of molecules in the products and reactants?
The letter that represents heat transfer.
What is q?
What is q(surr) = -q(sys)?
While reaction rate is indicative of this, spontaneity is not.
What is reaction speed?
The units in which Enthalpy is typically measured.
What is kJ/mol?
The state of matter that has the lowest entropy.
What are solids?
This matters less when the reaction starts at a higher original temperature.
What is change in temperature?
In thermodynamics, k is a constant that represents this number.
What is 1.34 x 10^-23 J/K?
The two factors that effect spontaneity.
What is change in enthalpy and entropy?
The type of reaction that occurs when the strength of bonds in the products is stronger than those of the reactants.
What is an exothermic reaction?
The things that happens to entropy when the temperature increases.
What is increase?
When deltaS is unfavorable, but the process is still spontaneous, this must be true of the reaction.
What is exothermic?
A graph like this indicates this type of reaction:
______
/ \
--------/ \
\
\----------
What is exothermic?
A reversible process does not have a change in this.
The state of deltaH that describes when the strength of bonds in the reactants is stronger than those of the products.
What is unfavorable?
The formula for entropy.
What is S = k ln(W)?
The relationship between entropy and heat transfer.
What is deltaS(surr) = -q(surr)/T?
The concept predicts whether a process will occur or not.
What is Thermodynamics?
