Practice Questions

Question 1

According to Le Chatelier's principle, what happens to the position of equilibrium if the concentration of a reactant is increased in a reversible reaction at equilibrium?

Question 2

In an exothermic reaction, how does a decrease in temperature affect the equilibrium position according to Le Chatelier’s principle?

Question 3

Which of the following changes would shift the equilibrium position of the reaction $\text{N}_2(g) + 3\text{H}_2(g) \rightleftharpoons 2\text{NH}_3(g)$ to the right?

Question 4

For the equilibrium reaction $\text{PCl}_5(g) \rightleftharpoons \text{PCl}_3(g) + \text{Cl}_2(g)$, what happens if the pressure is increased at constant temperature?

Question 5

For the reaction $\text{H}_2(g) + \text{I}_2(g) \rightleftharpoons 2\text{HI}(g)$, what will happen to the equilibrium position if more hydrogen gas (H$_2$) is added?
