Derive Ea from rate constants measured at two temperatures, given k1 at T1 and k2 at T2

Derive Ea from rate constants measured at two temperatures, given k1 at T1 and k2 at T2

• A. Ea = R ln(k2/k1) / (1/T1 - 1/T2)
• B. Ea = R ln(k2/k1) / (1/T2 - 1/T1)
• C. Ea = -R ln(k2/k1) / (1/T1 - 1/T2)
• D. Ea = R ln(k1/k2) / (1/T1 - 1/T2)

Answer: (A)
