Arrhenius Equation – AP Chemistry

Learning Objectives

Apply k = A·e^(−Ea/RT)

Interpret ln(k) vs 1/T plot (slope = −Ea/R)

Predict how temperature affects reaction rate

Compare catalyzed vs uncatalyzed reactions

Key Equations

k = A·e^−Ea/(RT)
ln(k) = ln(A) − Ea/(RT)
R = 8.314 J/(mol·K)
Two-point: ln(k₂/k₁) = −Ea/R(1/T₂ − 1/T₁)
