A few real AP Chemistry questions with answers and step-by-step solutions, in the exact style of the full mock tests.
What is the molecular geometry of SiCl₄?
Solution: By VSEPR theory, SiCl₄ is tetrahedral.
A gas occupies 6 L at 3 atm. At constant temperature, what volume does it occupy at 6 atm?
Solution: P₁V₁ = P₂V₂ ⇒ V₂ = 3 × 6/6 = 3 L.
A reaction has a theoretical yield of 21 g. The actual yield is 13.65 g. What is the percent yield?
Solution: 13.65/21 × 100 = 65%.
A first-order reaction has a half-life of 20 min. What is its rate constant?
Solution: k = 0.693/t½ = 0.693/20 = 0.0347 min⁻¹.
Reaction 1: A → B, ΔH = -40 kJ. Reaction 2: B → C, ΔH = 186 kJ. What is ΔH for A → C?
Solution: Hess's law: A → B (-40) + B → C (186) = 146 kJ.
For A(g) + B(g) ⇌ 2C(g), equilibrium concentrations are [A] = 1 M, [B] = 1 M and [C] = 0.4 M. What is Kc?
Solution: Kc = [C]²/([A][B]) = 0.4²/(1 × 1) = 0.16.
