Question

The maximum external work that can be obtained from a system is represented by

Answer 1

Answer:

The maximum external work that can be obtained by the system is represented by Gibb's Free Energy.

Explanation:

All chemical reactions that take place without the assistance of external energy tend to result in the creation of bodies or systems of bodies that release heat is known to be maximum work.

Gibbs Free energy used to calculate the maximum work performed in a thermodynamic system with constant temperature and pressure. G is used to represent Gibbs free energy. Typically, its value is stated in joules or kilojoules. The maximum amount of work that may be wrung out of a closed system is known as Gibbs free energy.

The energy that a substance has available for utilization in a chemical reaction or transformation is known as the Gibbs free energy. Things frequently change into other things that have less Gibbs free energy. The Gibbs free energy change indicates whether a chemical reaction will take place spontaneously or not.

The following conditions must be met for maximum work:

• All system modifications made throughout the process are reversible.
• The system should undergo all changes throughout the procedure in incredibly small, endless increments.
• The driving and opposing forces should differ during the transition by an incredibly tiny amount.
• The environment and the system continue to be in mechanical equilibrium.

Answer 2

1. Maximum work is performed during an ideal gas's isothermal reversible expansion.
2. The following are the requirements for maximal work:
3. Every alteration that occurs in the system throughout the process is reversible.
4. Every change that occurs in the system throughout the process should occur in infinitesimally small steps.
5. The driving and opposing forces should only alter by the tiniest amount during the transition.
6. The system continues to be in mechanical equilibrium with its environment.
7. Maximum effort is described as:   ​$W_{max}=-2.303nRTlog\frac{P1}{P2}$

Explanation:

• It is well known that all chemical reactions that occur without the aid of outside energy produce bodies or systems of bodies that emit heat. This is known as maximal work.
• In a thermodynamic system with constant temperature and pressure, the maximum work can be calculated using Gibbs free energy.
• The Gibbs free energy symbol is G. Usually, its energy content is expressed in joules or kilojoules. Gibbs free energy is the most work that might possibly be extracted from a closed system.
• Gibbs free energy is the amount of energy that a substance can expend during a chemical reaction or transition.
• Objects commonly transform into different things with lower Gibbs free energy.
