Equilibrium

Question 1

What happens to the position of equilibrium and value of Kc if an exothermic reaction is heated?

Answer 1

Equilibrium shifts to the left Kc decreases

Question 2

What happens to the position of equilibrium and value of Kc if an exothermic reaction is cooled?

Answer 2

Equilibrium shifts to the right Kc increases

Question 3

What happens to the position of equilibrium and value of Kc if an endothermic reaction is heated?

Answer 3

Equilibrium shifts to the right Kc increases

Question 4

What happens to the position of equilibrium and value of Kc if an endothermic reaction is cooled?

Answer 4

Equilibrium shifts to the left Kc decreases
