Which of the conditions is always true at equilibrium? True at equilibrium Not necessarily true at equilibrium

The reaction must be involved in a reversible chemical process no matter how small the extent of the reversibility.
The rate of forward process is equal to the rate of backward process.
The system is closed i.e energy cannot be exchanged.
The free energy change of the system is zero
There is no change in concentration of each of the species in equilibrium with respect to time.
The system offers resistance to any change in any of the factors governing the equilibrium.

True at equilibrium

a. [tex]\Delta G= 0[/tex] is true

Not true at equilibrium

[tex]\Delta G= \Delta G^\circ\\\Delta G^\circ= 0\\Q = 10\\\Delta G^\circ = 1\\Q = 1\\k = 1[/tex]

What is chemical equilibrium?

Chemical equilibrium is reached when the rate of forwarding reaction is equal to the rate of backward reaction.

Chemical equilibrium is a state in which no net increase in the quantities of reactants and products happens during a reversible chemical reaction.

A reversible chemical reaction occurs when the products react with the original reactants as soon as they are generated.

Thus, True at equilibrium

a. [tex]\Delta G= 0[/tex] is true

Not true at equilibrium

[tex]\Delta G= \Delta G^\circ\\\Delta G^\circ= 0\\Q = 10\\\Delta G^\circ = 1\\Q = 1\\k = 1[/tex]
