Hint :The phrase steady state can also refer to a scenario in which some, but not all, of a system's state variables are constant. The system does not have to be a flow system to generate such a steady state. As a result, in a closed system with a succession of chemical processes, such a steady state can emerge. This scenario is commonly referred to as steady state approximation in chemical kinetics literature.
Complete Step By Step Answer:
As far as I know, when two systems are in "thermal equilibrium," heat is transferred between them and their temperatures are equal, but when they are in a "steady state of heat transfer," heat enters the system and heat exits the system. However, the temperature does not change.
Let's get to the chemical balance. There are times when A becomes B and B becomes A in a chemical equilibrium between A and B. (There is a transfer between A and B, yet there is a net change in A and B's extent.) As a result, it reminds me of the idea of "stationary state." Our understanding of "equilibrium" is skewed.
Note :
The idea of steady state differs from that of chemical equilibrium. Although both can result in a condition where a concentration does not vary, the net reaction rate in a system in chemical equilibrium is zero (products convert into reactants at the same rate as reactants transform into products), but the steady state notion has no such restriction. A stable state can emerge without even requiring a response.

Steady State | Thermodynamic Equilibrium |
A steady state in chemistry is a condition in which all state variables remain constant despite continuous activities that attempt to alter them. | When two physical systems are connected by a heat-permeable channel, they are in thermal equilibrium if there is no net movement of thermal energy between them. |
There must be a flow through a system for it to be in steady state, that is, for all of its state variables to be constant (compare mass balance) | The zeroth law of thermodynamics governs thermal equilibrium. If the temperature within a system is geographically uniform and temporally constant, it is said to be in thermal equilibrium with itself. |
A basic example of such a system is a bathtub with the tap running but the drain unplugged: after a given amount of time, the water level (the state variable Volume) stabilises and the system is in a steady state. | Thermodynamically balanced systems are always thermally balanced, while the opposite is not necessarily true. |
