Reaction Feasibility

Question 0

What is the standard entropy

Answer 0

Entropy of a substance at a pressure of one atmosphere at 298K in J/MOL

Question 1

What is the entropy

Answer 1

Measure of disorder within a system - larger the entropy the larger disorder

Question 2

What is the third law of thermodynamics

Answer 2

Particles are in perfect order at 0K

As temp increases entropy of solid increases until melt point

Question 3

Straight line in graph shows a

Answer 3

Change of state

Question 4

What is a feasible Reaction

Answer 4

One which takes place of its own accord

Question 5

What is the second law of thermodynamics

Answer 5

For a reaction to be feasible the total entropy for a reaction system and it’s surroundings must be positive

Question 6

If the standard free energy change is less than 0

Answer 6

Will be feasible so products will predominate over the reactants
Equilibrium lie to right and K>1

Question 7

If the standard energy change is greater than 0

Answer 7

Reactants will predominate reaction feasible equilibrium lie to left k<1
