# Chemical Kinetics ## Reaction Rate **Rate**: $-d[A]/dt = k[A]^m[B]^n$ ## Rate Laws ### Zero-Order: * $[A] = [A]_0 - kt$ ### First-Order: * $ln[A] = ln[A]_0 - kt$ ### Second-Order: * $\frac{1}{[A]} = \frac{1}{[A]_0} + kt$ ## Half-Life ### First-Order: * $t_{1/2} = \frac{0.693}{k}$...
# Chemical Kinetics ## Reaction Rate **Rate**: $-d[A]/dt = k[A]^m[B]^n$ ## Rate Laws ### Zero-Order: * $[A] = [A]_0 - kt$ ### First-Order: * $ln[A] = ln[A]_0 - kt$ ### Second-Order: * $\frac{1}{[A]} = \frac{1}{[A]_0} + kt$ ## Half-Life ### First-Order: * $t_{1/2} = \frac{0.693}{k}$ ### Second-Order: * $t_{1/2} = \frac{1}{k[A]_0}$ ### Zero-Order: * $t_{1/2} = \frac{[A]_0}{2k}$ ## Arrhenius Equation: * $k = Ae^{-E_a/RT}$ ## Linear Arrhenius Form: * $ln k = -\frac{E_a}{R} \frac{1}{T} + ln A$ ## Integrated Rate Laws: ### Zero-Order: * $[A] = [A]_0 - kt$ ### First-Order: * $ln[A] = ln[A]_0 - kt$ ### Second-Order: * $\frac{1}{[A]} = \frac{1}{[A]_0} + kt$
