Test your understanding with targeted questions related to the topic.
Question 1
Easy
If 2.0 mol of A is placed in a 5.0 dm³ container, what is the initial concentration of A?
💡 Hint: Use the formula: concentration = moles/volume.
Question 2
Easy
In the reaction C ⇌ D, if the initial concentration of D is 0.20 mol/dm³ and no C is present, write the initial conditions in an ICE table.
💡 Hint: Remember to fill out all initial values for the ICE table.

Question 1
If you start with 0.40 mol of C in a 2.0 dm³ container, and the reaction C ⇌ 2D has Kc = 0.1, calculate equilibrium concentrations using ICE.
💡 Hint: Make sure your expressions for changes reflect the stoichiometry.
Question 2
For the reaction N₂ + 3H₂ ⇌ 2NH₃, starting with 1.0 mol of N₂ in a 5.0 dm³ and with Kc = 0.3, calculate equilibrium concentrations.
💡 Hint: Consider if an approximation is valid before performing calculations.
