∆G equation

Question 1

∆H is negative
∆S is positive

Answer 1

∆G negative- feasible
As temp inc, ∆G more negative, more feasible

Question 2

∆H is positive
∆S is negative

Answer 2

∆G positive- not feasible
As temp inc, ∆G more positive, less feasible

Question 3

∆H is negative
∆S is negative

Answer 3

∆G negative when temp lower
Reaction feasible at low temp
As temp inc, ∆G more positive, less feasible

Question 4

∆H positive
∆S positive

Answer 4

∆G negative when temp higher
Reaction feasible at high temp
As temp inc, ∆G more negative, more feasible

Question 5

∆G graph equation

Answer 5

∆G= -∆ST + ∆H
