Recent questions

• What is chemical equilibrium?

  Chemical equilibrium is a state in a reaction where the forward and backward reactions occur at the same rate, resulting in no net change in the concentrations of reactants and products.

• How do reversible reactions differ from irreversible reactions?

  Reversible reactions can proceed in both forward and backward directions, while irreversible reactions only occur in one direction, leading to the formation of products that cannot revert back to reactants.

• What are the three possibilities in chemical reactions?

  Chemical reactions can involve breakdown, combination, or displacement of substances, leading to the formation of different products based on the nature of the reaction.

• What is the significance of the rate of reactions in achieving equilibrium?

  The rate of reactions determines how quickly a reaction reaches equilibrium, with reversible reactions being able to shift in both directions until a balance is achieved between reactants and products.

• How does a change in weight on one side affect the balance in chemical equilibrium?

  Just like a physical balance, a change in weight on one side of a chemical equilibrium reaction can shift the equilibrium towards the side with less weight, altering the concentrations of reactants and products until a new equilibrium is established.
