Unit 9: Applications of Thermodynamics

Question 1

Two kinds of processes that increase entropy?

Answer 1

•Temperature
•Shape of state space

Question 2

How does entropy increase?

Answer 2

When energy becomes more dispersed.

Question 3

When volume increase, entropy decrease/increase?

Answer 3

Increase

Question 4

Kinetic molecular theory (KMT)?

Answer 4

As the temperature increase, kinetic energy varies more within different molecules in a gas. This can be viewed in the maxwell-Boltzmann distribution in which if variance increases, temperature increases and the variation in kinetic energy is because variance increases.

Question 5

DeltaS = ?

Answer 5

Sum(S_products) - sum(S_reactants)

Question 6

Do all thermodynamically favourable events occur?

Answer 6

No since their reaction rates are extremely.

Question 7

What does it mean for a favourable reaction to be under kinetic control?

Answer 7

When the reaction does not proceed by controlling the activation energy.

Question 8

How is K related to free energy?

Answer 8

DeltaG = -R T ln(K)
