Irreversible process work done
WebAnswer: No. Workdone in reversible is always more than the workdone in irreversible. The reason is the system has to work against the gradual higher external pressure in reversible condition. Whereas the external pressure is constant, no rising in irreversible condition, hence work is less. WebDetails. Expansion-compression work for all four processes is calculated from. where is the external pressure and is in units of kJ/mol. The external pressure and the gas pressure are equal for a reversible process, whereas for an irreversible process the external pressure is the final pressure.

WebA reversible process is a process in which the system and environment can be restored to exactly the same initial states that they were in before the process occurred, if we go … WebIn thermostatics, the two bounds on work (the upper bound on the work produced and the lower bound the work consumed) do coincide. But the static limits are often too far from …
WebJan 5, 2024 · Reversible work means that the entire system (including the surrounding system) can be returned to the starting state. Irreversible work means that we can only … In the physical realm, many irreversible processes are present to which the inability to achieve 100% efficiency in energy transfer can be attributed. The following is a list of spontaneous events which contribute to the irreversibility of processes. • Ageing (this claim is disputed, as aging has been demonstrated to be reversed in mice. NAD+ and telomerase have also been demonstrated to reverse ageing.)
WebSep 12, 2024 · The work done by the gas in the expansion is d W = p d V; d Q = 0 because the cylinder is insulated; and the change in the internal energy of the gas is d E i n t = C V n d T. Therefore, from the first law, C V n d T = 0 − p d V = − p d V so d T = − p d V C V n. Also, for 1 mol of an ideal gas, [d (pV) = d (RnT), \nonumber\] so WebThe irreversible process known as Joule heating also occurs through a change of a non-deformation extensive state variable. Accordingly, in the opinion of Lavenda, work is not as primitive concept as is heat, ... Work …
