New cards

Spontaneity

  • Processes are spontaneous when they result in an increase in disorder 

  • The total energy of the universe is constant, but the entropy is increasing

2
New cards

Law of Thermodynamics

  • In any spontaneous process, there is always an increase in the entropy of the universe 

  • Energy is conserved in the universe, but entropy is not 

3
New cards

∆Suniv =

∆Suniv =  ∆Ssys + ∆Ssurr 

4
New cards

if ∆Suniv is positive then

entropy of the universe increases and the process is spontaneous in the direction written

5
New cards

if ∆Suniv is negative then

the process is spontaneous in the opposite direction

6
New cards

if ∆Suniv is 0 then

 process has no tendency to occur, indicating that the system is at equilibrium
