Final Exam Flashcards
Measure of chaos within a system
Entropy
Do gases have low or high entropy?
High
Do solids have low or high entropy?
Low
A change from low entropy to high entropy has a positive or negative ΔS?
Positive ΔS
As entropy increases does the amount of moles increase or decrease?
Decrease
Positive ΔS favors spontaneity or non-spontaneity?
Spontaneity
What happens to ΔG when put in a reversed reaction?
It remains the same value but the sign becomes opposite
Do low activation energy reactions or high activation energy reactions have a high reaction rate?
Low activation energy reactions
Energy required for a reaction to occur
Activation Energy E_a
Does a catalyst increase or decrease the activation energy?
Decrease
Does a catalyst increase or decrease the rate of a reaction?
Increase
Does an increase in concentration increase or decrease the rate of a reaction?
Increase
Does an increase in temperature increase or decrease the rate of a reaction?
Increase
If the rate of the reaction is equal to the rate of the reversed reaction this is an example of?
Equilibrium
Equilibrium constant
K=[C]^c[D}^d/[A]^a[B]^b
Reaction: aA+bB–> cC+dD
