Read the following paragraph and answer the questions given below , Stable equilibrium is of various type . Mechanical equilibrium is achieved when all particles are at rest and total potential energy of the system is minimum . At any stage where particles are at rest but the system is not at stabel equilibrium as it can reduce its potential energy by reverting to another position, is called metastable equilibrium . Thermal equilibrium is result from the absence of temperature gradients in the system. chemical equilibrium is obtained when no further reaction occurs between reacting substances, i.e forward and reverse rates of reaction are equal. when steam with solid iron at high temperature Fe_3O_4(s) and hydrogen gas are produced . But the reaction never goes to completion. this is because as the products are formed the reaction proceeds in reverse direction and when rate of reverse reaction is equal to rate of forward reaction , the concentration of reactants and products become constant and equilibrium is reached. The correct expression for equilibrium constant of the reaction, taken as an example of chemical equilibrium in the above passage is

When a matchbox is balanced on its edge, it is unstable and will tumble to a more stable position resting on its face so as to acquire minimum potential energy. This is an example of

Which one of the following statements is wrong? a. Physical adsorption of gas directly related to its critical temperature. b. Chemical adsorption decreases regularly as the temperature is increased. c. Adsorption is an exothermic process. d. A solid with a rough surface is a better adsorbent than the same solid with a smooth surface.

Physical and chemical equilibria can respond to a change in their pressure, temperature, and concentration of reactants and products. To describe the change in the equilibrium, we have a principle named Le Chatelier's principle. This we can define in terms of energy, as the free energy change in equilibrium is zero means the system is stable. So if we are doing some changes in equilibrium, then the system having a tendency to reestablish the equilibrium by undoing the effect we brought. Consider the following equilibrium. Three sparingly soluble salts A_(2)B, AB , and AB_(3) are given. If all the three having the same value of solubility products (K_(sp)) , in the saturated solution, the correct order of their solubilites is

Which of the following statement(s) is/are incorrect: Statement (a) : Reversible isothermal compression of an ideal gas represents the limiting minimum value of the workdone (lwl) by the surrounding on the system.

Statement (c) : For thermodynamic changes in adiabatic process ""_(T)((C_(p.m))/(R)).P = constant Statement (d) : DeltaS_("system") is zero for reversible adiabatic expansion of an ideal gas.
