Give one example for each of the following processes-
(i) `DeltaP` (system)=0 (ii) `DeltaV`(system)=0
(iii) `DeltaT` (system)=0
(iv) q=0
(v) `DeltaU`(system)=0.

Give an example of a process where q=0

Define the following with examples: (i) Open system, (ii) Closed system, (iii) Isolated system.

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 .

Give an example of a process for each of the given cases: (1) DeltaG=0, DeltaS gt0 (2) DeltaG=0,DeltaS lt 0 (3) DeltaG lt 0, DeltaS gt0 (4) DeltaG lt 0, DeltaS lt 0 in a system.

Give definition: (i) closed system (ii) adiabatic system (iii) open system (iv) isolated system.

Give two examples of spontaneous processes in which disorderliness of the system decreases.

Give an example of a spontaneous process in which the change in enthalpy of the system is positive.

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
