Reversible Reactions and Equilibria

Question 1

How can a reversible reaction reach dynamic equilibrium?

Answer 1

In a closed system

Question 2

What are the characteristics of a reaction at dynamic equilibrium?

Answer 2

Forward and reverse reactions occur at the same rate
Concentrations of reactants and products remain constant

Question 3

What is the effect of increasing temperature?

Answer 3

Shifts the position of equilibrium in the direction of the endothermic reaction

Question 4

What is the effect of decreasing the temperature?

Answer 4

Shifts the position of equilibrium in the direction of the exothermic reaction

Question 5

What is the effect of increasing the pressure?

Answer 5

Shifts the position of equilibrium in the direction that produces fewer molecules of gas

Question 6

What is the effect of decreasing the pressure?

Answer 6

Shifts the position of equilibrium in the direction that produces more molecules of gas

Question 7

How does a catalyst affect the position of equilibrium in a reversible reaction?

Answer 7

It doesn’t affect the position because it speeds up the forward and backward reaction by the same amount
