The following information will be provided on the exam:

K = °C + 273
R = 0.08206 Latm/mol· K = 8.314 J/mol· K

[A] = [A]_o - kt

ln[A] = ln[A]_o - kt
ln ([A]/[A]_o) = -kt
kt_½ = ln2 = 0.693

1/[A] = 1/[A]_o + kt

k = Ae^-Ea/RT
ln k = ln A - (Ea/R)(1/T)
ln (k₂/k₁) = (-E_a/R)(1/T₂ - 1/T₁)

K_p = K_c (RT)^{D n}

pH = - log [H₃O⁺]
pOH = - log [OH^-]

At 25 ° C:
[H₃O⁺] [OH^-] = 1.0 x 10^-14
pH + pOH = 14
