6.2 Reversible reactions and dynamic equilibrium

• At equilibrium, the rate of the forward reaction equals the rate of the reverse reaction.


  True
• At equilibrium, the concentrations of reactants and products remain constant.


  True
• What is the sign of equilibrium in a reversible reaction?

  Constant concentrations
• Define dynamic equilibrium.

  Forward and reverse rates equal
• What is dynamic equilibrium defined as?

  Equal rates of forward and reverse reactions
• Match the reaction direction with its process:

  Forward reaction ↔️ Reactants → Products

  Reverse reaction ↔️ Products → Reactants
• What is the rate relationship between forward and reverse reactions in a reversible reaction at equilibrium?

  Equal rates
• What is a reversible reaction?

  Products form original reactants
• In a reversible reaction, there are two key processes: the forward and the reverse
• What is the reverse reaction in a reversible reaction?

  Products → Reactants
• At equilibrium in a reversible reaction, the rate of the forward reaction equals the rate of the reverse
• Describe a reversible reaction.

  Products form original reactants
• In dynamic equilibrium, the rates of the forward and reverse reactions are the same.


  True
• One characteristic of dynamic equilibrium is that the rates of forward and reverse reactions are identical
• Reversible reactions at equilibrium have constant concentrations of reactants and products.

  True
• Le Chatelier's principle predicts how equilibrium shifts in response to altered conditions.


  True
• Match the reaction type with its description:

  Forward Reaction ↔️ Reactants → Products

  Reverse Reaction ↔️ Products → Reactants
• Order the processes in a reversible reaction:

  1️⃣ Reactants are converted to products

  2️⃣ Products are converted back to reactants

  3️⃣ Equilibrium is reached
• In a reversible reaction, the forward and reverse processes occur simultaneously.


  True
• Dynamic equilibrium is a state where the rate of the forward reaction is equal to the rate of the reverse
• In dynamic equilibrium, there is a net change in concentrations over time.

  False
• The reverse reaction in a reversible reaction converts products back into reactants
• Order the effects of changes in conditions on equilibrium according to Le Chatelier's principle:

  1️⃣ Increase Concentration of Reactants → Shifts to favor product formation

  2️⃣ Increase Pressure (for gases) → Shifts to the side with fewer moles of gas

  3️⃣ Increase Temperature → Shifts to favor endothermic reaction
