How `DeltaG` is related to `DeltaH and DeltaS`? What is the meaning of `DeltaG = 0`?

The relation of DeltaH and DeltaE is represented as

How are Delta H and Delta U are related? What is the difference between Delta Hand Delta U in a fusion process?

Give the relation between DeltaU and DeltaH .

Establish DeltaG = DeltaH- TDeltaS .

A reaction is spontaneous at low temperature but non spontaneous at high temperature. Which of the following (1) DeltaH gt 0, DeltaS gt 0 (2) DeltaH lt 0, DeltaS lt 0 (3) DeltaH gt 0, DeltaS = 0 (4) DeltaH lt 0, DeltaS lt 0 (5) DeltaH = 0, DeltaS lt 0

Predict the feasibility of a reaction when i) both DeltaH and DeltaS increase ii) both DeltaH and DeltaS decrease iii) DeltaH decreases but DeltaS increases

At the sublimition temperture, for the process CO_2(s) iff CO_2(g) (1) DeltaH, DeltaS and DeltaG are all positive (2) DeltaH gt 0, DeltaS gt 0 and DeltaG lt 0 (3) DeltaH lt 0, DeltaS gt 0 and DeltaG lt 0 (4) DeltaH gt 0, DeltaS gt 0 and DeltaG gt 0 (5) DeltaH gt 0, DeltaS gt 0 and DeltaG = 0

Give an example of a reaction for each of the following relations between DeltaH and DeltaU : (i) DeltaU lt DeltaH (ii) DeltaU gt DeltaH (iii) DeltaU=DeltaH .

DeltaG of the system alone provides a criterion for the spontaneity of a process at constant temperature & pressure, DeltaG system lt 0 (spontaneous) DeltaG system = 0 (equilibrium) DeltaG system gt 0 {(non-spontaneous) Again DeltaG^@ is related to the equilibrium constant as follows : DeltaG^@ = 2.303 RT log K_e If both DeltaH and Delta S are negative, the reaction will be spontaneous
