Concept explainers
(a)
Interpretation:
If heat is removed from a system which is not adiabatic, then the immediate response of the system in liquid-gas equilibrium is to be predicted.
Concept introduction:
According to the Le Chatelier’s principle the change in concentration, volume, pressure and temperature affects the equilibrium constant of the reaction. The equilibrium shifts in such a way or a direction that it reduces the effect of change.
(b)
Interpretation:
If heat is added to a system which is not adiabatic, then the immediate response of the system in solid-gas equilibrium is to be predicted.
Concept introduction:
According to the Le Chatelier’s principle the change in concentration, volume, pressure and temperature affects the equilibrium constant of the reaction. The equilibrium shifts in such a way or a direction that it reduces the effect of change.
(c)
Interpretation:
If heat is removed from a system which is not adiabatic, then the immediate response of the system in liquid-solid equilibrium is to be predicted.
Concept introduction:
According to the Le Chatelier’s principle the change in concentration, volume, pressure and temperature affects the equilibrium constant of the reaction. The equilibrium shifts in such a way or a direction that it reduces the effect of change.
(d)
Interpretation:
If heat is removed from a system which is not adiabatic, then the immediate response of the system which is composed entirely of solid phase is to be predicted.
Concept introduction:
According to the Le Chatelier’s principle the change in concentration, volume, pressure and temperature affects the equilibrium constant of the reaction. The equilibrium shifts in such a way or a direction that it reduces the effect of change.

In the first stage, the system is compressed at a constant temperature. As a result of this process, the volume of the system decreases from 1.8 to 0.4 liters. In the second stage, heat is given to the system at the constant pressure obtained at the end of the first stage. If at the beginning of the first phase If the pressure is 1 atm, what will be the volume of this system after giving 320 kJ of heat to the system in the second stage?arrow_forward
