The correct Answer is:
**Step-by-Step Solution:** 1. **Understanding the Assertion**: The assertion states that "The living state is an equilibrium steady state not able to perform work." To analyze this, we need to define what an equilibrium state is. In an equilibrium state, there is no tendency for the system to change spontaneously, and it cannot perform work. 2. **Evaluating the Living State**: Living organisms are not in a state of equilibrium. They are dynamic systems that require energy to maintain their structure and function. They perform work to sustain life processes, which contradicts the assertion that they are in an equilibrium state. 3. **Understanding the Reason**: The reason states that "Living process is a constant effort to prevent falling into non-equilibrium." This implies that living organisms are constantly working to maintain their internal environment against external changes, which is true. 4. **Linking Assertion and Reason**: While the reason is true, it does not correctly explain the assertion. The assertion is incorrect because living organisms are not in a state of equilibrium; they are in a steady state that requires continuous energy input to maintain. 5. **Conclusion**: Both the assertion and the reason are false. The assertion is incorrect because living organisms are not in an equilibrium state, and the reason, while true, does not provide a correct explanation for the assertion. **Final Answer**: Both the assertion and the reason are false. ---

Comment on the statement 'living state is a non-equilibrium steady state to be able to perform work :

Select the incorrect statement from the following : (i) Biomolecules are in metabolic flux in the living state . (ii) Living process is a constant effort to prevent falling into equilibrium (iii) Metabolism provides a mechanism for the production of energy (iv) Living state and metabolism is synonymous

Assertion : The equilibrium constant for the reverse reaction is equal to the inverse of the equilibrium constant for the forward reaction . Reason : The value of equilibrium constant is independent of initial concentrations of the reactants and products.

Assertion : The first living organisms on earth were autotrophs. Reason : They were capable of performing chemosynthesis.

Assertion : Living organisms show internal as well as external growth. Reason : Living organism undergo the process known as accretion.

Assertion: Bernoulli's equation hold for non-steady or turbulent flows. Reason: In these situations, velocity and pressure are constant with time.

Assertion : A quasi static isothermal expansion of an ideal gas in a cylinder fitted with a frictionless movable pistonis a irreversible process. Reason : A process is irreversible only if system remains in equilibrium with the surroundings at every stage.

Assertion (A): For every chemical reaction at equilibrium, standard Gibbs enegry of the reaction is zero. Reason (R ) : At constant temperature and pressure chemical reactions are spontaneous in the direction of the decreasing Gibbs energy.

Assertion : The additions of an inert gas at constant volume to a system at equilibrium does not affect the state of equilibrium Reason: The inert gas does not react with any of the reactants or products.

Assertion (A) : For PCl_(5)(g) hArr PCl_(3)(g)+Cl_(2)(g) , if more Cl_(2) is added the equilibrium will shift in backward direction. Hence, equilibrium constant will decrease. Reason (R) : Addition of inert gas to the equilibrium mixture at constant volume does not alter the equilibrium.
