Challenge Problems

Push your limits with challenges.

Question 1

Consider the reaction: 2 NO(g) + O₂(g) ⇌ 2 NO₂(g). If the Kc is 5.0 at a certain temperature, and you start with 0.50 M of NO and 0.25 M of O₂, calculate the equilibrium concentrations.

💡 Hint: Remember to consider stoichiometry while setting up the Kc expression.

Question 2

In the exothermic reaction: A(g) + B(g) ⇌ C(g) + heat, if the Kc is 0.10 at equilibrium and the initial concentrations of A and B are both 2.0 M, find the concentration of C at equilibrium.

💡 Hint: Keep track of how the change in C relates to the changes in A and B.
