Question:

Activation energy (Ea) and rate constant (k1 and k2) of a chemical reaction at two different temperatures (T1 and T2) are related by:

ln(k2/k1) = -Ea/R(1/T1 - 1/T2)

ln(k1/k2) = Ea/R(1/T1 - 1/T2)

ln(k2/k1) = -Ea/R(1/T2 + 1/T1)

ln(k2/k1) = -Ea/R(1/T2 - 1/T1)

Solution:

Activation energy (Ea) and rate constant (k1 and k2) of a chemical reaction at two different temperatures (T1 and T2) are related by Arrhenius equation which can be represented as either ln(k2/k1) = -Ea/R(1/T1 - 1/T2) or ln(k2/k1) = -Ea/R(1/T2 - 1/T1).
