For a process at equilibrium
`ΔS _(total) >0`
`ΔH_(SYS)=0`
`ΔG_(TP) <0`
`ΔS _(total)=0`

For adiabatic process, DeltaH = 0

For an isobaric process, DeltaP=0 .

A process is non-spontaneous when DeltaS_("total") lt 0 .

For a process Delta S_("total") = 0 and Delta G = 0 was obtained. What does it mean?

At 25^(@)C and 1 atm pressure, the partial pressure in equilibrium mixture of N_(2)O_(4) and NO_(2) , are 0.7 and 0.3 atm , respectively. Calculate the partial pressures of these gases when they are in equilibrium at 25^(@)C and a total pressure of 10 atm .

Calculate the volume percent of chlorine gas at equilibrium in the dissociation of PCl_(5)(g) under a total pressure of 1.5 atm. The K_(p) for its dissociation =0.3 .

For a process DeltaS_(total ) = 0 and Delta G = 0 was obtained. What does it mean?

Solid NH_(4)HS(s) (ammonium hydrogen sulphate) dissociates to give NH_(3)(g) and H_(2)S(g) and is allowed to attain equilibrium at 100^(@)C . If the value of K_(p) for its dissociation is found to be 0.34 , find the total pressure at equilibrium at 100^(@)C . If the value of K_(p) for its dissociation is found to be 0.34 , find the total pressure at equilibrium and partial pressure of each component.

A change in the free energy of a system at constant temperature and pressure will be: Delta_(sys)G = Delta_(sys)H -T Delta_(sys)S At constant temperature and pressure Delta_(sys) G lt 0 (spontaneous) Delta_(sys)G = 0 (equilibrium) Delta_(sys)G gt 0 (non-spontaneous) For a spontaneous reaction DeltaG , equilibrium K and E_(cell)^(Theta) will be, respectively

A cube of side a is placed in a uniform electric field E = E_(0) hat(i) + E_(0) hat(j) + E_(0) k . Total electric flux passing through the cube would be
