Practice Questions

Question 1

In equilibrium calculations, what does the term equilibrium concentration mean?

Question 2

For the equilibrium $N_2(g) + 3H_2(g) \rightleftharpoons 2NH_3(g)$, which expression is correct for $K_c$?

Question 3

If $K_c$ is very large for a reaction at equilibrium, what does that usually mean?

Question 4

A reaction starts with $[A] = 0.80\,\text{mol dm}^{-3}$ and $[B] = 0.40\,\text{mol dm}^{-3}$. If the equilibrium concentration of $A$ is $0.50\,\text{mol dm}^{-3}$, how much $A$ was consumed?

Question 5

In an ICE table, what does the letter $I$ stand for?
