Question

Equilibrium is established in a reversible reaction when: the [product] = [reactants] rate of reaction of products = rate of reaction of reactants all the reactants dissolve or dissociate product is no longer produced

Answer 1

Answer:

the [product] = [reactants]

rate of reaction of products = rate of reaction of reactants

Explanation:

The equilibrium state is a state of rest or motion of system. A chemical equilibrium is dynamic in nature.

These are the conditions for a system to be in equilibrium:

• it must be involved in reversible chemical processes no matter the extent of the reversibility.
• the rate of forward reaction must be equal to that of the 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 the concentration of each of the species in equilibrium with respect to time. This implies that concentration is constant.
• The system offers resistance to any change in any of the factors governing the equilibrium.
