Reversible Reactions And Equilibria

Question 1

NH4Cl(s)

Answer 1

NH3(g)+HCl(g)

Question 2

CuSO4.5H2O(s)(blue)

Answer 2

CuSO4(s)(white)+5H2O(l)

Question 3

When does a reversible reaction reach dynamic equilibrium?

Answer 3

In a sealed container

Question 4

What happens in dynamic equilibrium?

Answer 4

• The forward and reverse reactions occur at the same rate
• The concentrations of reactants and products remain constant

Question 5

Why does a catalyst have no effect on the position of equilibrium?

Answer 5

It speeds up both the forward and backward reactions equally

Question 6

Which way does an increase in temperature shift the position of equilibrium?

Answer 6

In the direction of the endothermic reaction

Question 7

Which way does an increase in pressure shift the position of equilibrium?

Answer 7

In the direction that produces fewer moles of gas
