Irreversible process vs reversible process

Postby Emma Ward 2C » Fri Jan 12, 2018 3:41 pm

Can someone explain to me the difference between irreversible and reversible processes?? Really confused

I looked this topic up the other day and found this useful site: http://www.brighthubengineering.com/the ... processes/

To my understanding, an irreversible reaction can only go in one direction, such that when the reactants react to become the product, the product cannot convert back into reactants. These reactions are represented with a unidirectional arrow, and can never be at equilibrium. On the contrary, reversible reactions can convert back and forth between products and reactants, and can be at equilibrium.

Hope this helps!

An irreversible reaction is a reaction where one can not take the products and revert them back to the reactants; these reactants are usually represented with an arrow pointing towards the products because there is no going back. Whereas a reversible reaction one can go from the reactants to the products and vice versa, as said above represented with equilibrium arrows.

An irreversible process is expansion against an external pressure such that an infinitesimal change in the external pressure does not reverse the direction. A reversible process is expansion that can be reversed by an infinitesimal change.

For example, in an irreversible process, a piston can only move in or only move out. But in a reversible process, a piston can move both directions.
