ACS General Chemistry Exam Formula Sheet: 2025 Prep

Ace your ACS General Chemistry Exam with our ACS general chemistry exam formula sheet, updated for July 2025. This guide provides critical formulas, explanations, and tips tailored for test day, ensuring you’re well-prepared for this standardized assessment.

Why Use This Formula Sheet?

The ACS exam tests a broad range of chemistry concepts, from stoichiometry to thermodynamics. This formula sheet, with a search volume of 70 in July 2025, is designed to help students quickly reference key equations and apply them effectively.

Important Formulas

1. Equilibrium Constant

$K_c = \frac{[C]^c[D]^d}{[A]^a[B]^b}$

• Application: Quantify equilibrium concentrations.
• Example: For $2A + B \leftrightarrow C$, if [A] = 0.1 M, [B] = 0.2 M, [C] = 0.5 M, calculate ( K_c ).

2. Rate Law

$Rate = k[A]^m[B]^n$

• Application: Analyze reaction kinetics.
• Example: If ( k = 0.1 ) M⁻¹s⁻¹, [A] = 0.2 M, m = 1, Rate = ( 0.1 \times 0.2 = 0.02 ) M/s.

3. Nernst Equation

$E = E^0 - \frac{RT}{nF} \ln Q$

• Variables:
  • ( E ): Cell potential
  • ( E^0 ): Standard potential
  • ( Q ): Reaction quotient
• Application: Calculate cell potentials in electrochemistry.
• Example: For a cell with ( E^0 = 1.1 ) V, n = 2, at 298 K, Q = 0.1, calculate ( E ).

Exam Tips

• Memorize Key Formulas: Focus on equilibrium, kinetics, and electrochemistry.
• Practice Application: Solve ACS-style problems.
• Time Management: Prioritize questions you can solve quickly.
