In thermodynamics the symbols like `DeltaH`, `DeltaS` and `DeltaG` are commonly used.
What do the symbols `DeltaH`, `DeltaS` and `DeltaG` denote?

In thermodynamics the symbols like DeltaH , DeltaS and DeltaG are commonly used. how are they related?

For the reaction, 2Cl(g) rarr Cl_2(g) what are the signs of DeltaH and DeltaS ?

Write the condition of temperature for a process to be spontaneous whose DeltaH and DeltaS values are positive. [Hint: DeltaG = DeltaH - TDeltaS]

Observe the figure below and answer the questions following: what shows the shaded symbols used?

a) Name the instrument used for measuring the DeltaU of a process. b) What is the value of DeltaG for a reaction at equilibrium? c) DeltaH and DeltaS of a reaction are 30.56 and 0.666 kJ/mol respectively at 1 atm pressure. Calculate the temperature at which the reaction is in equilibrium.

Second law of thermodynamics deals with the spontanelty of a process. Iron is extracted from the ore Fe_2O_3 . Using the date given above suggest whether the decomposition of Fe_2O_3 is feasible or not. Substantiate. (DeltaH^@= 824 kJ//mol, DeltaS^@ + 0.276 kJ//mol K, T = 298 K).

Adsorption Is the phenomenon of higher concentration of particles on the surface than in the bulk of the solid.For adsorption, DeltaH = -ve . What is the sign of DeltaS for adsorption.?.
