What is the difference between Steady state and Equilibrium?

In my opinion;

Steady state: When the parameters (variables like speed , concentration) of a process doesn't change with time but the reaction keeps going on, then its a steady state condition. For example, flow of water in river. So,

Rate of input = rate of output

  • It occurs in open systems.

  • There is a net reaction.

  • Entropy will continuously increase.


Equilibrium state: A condition when the concentration of reactants and products will not change with time i.e.

Rate of forward reaction = Rate of backward reaction

  • It occurs in closed systems.

  • There is no net reaction, i.e., the reactions are reversible.

  • Entropy will remain constant @ equilibrium.
