Question

The temperature dependence of the rate of a chemical reaction is given by Arrhenius equation $k = Ae^{- E_{a}/RT}$ which of the following graphs will be straight line?

• A. ln A vs 1/T
• B. ln A vs $E_{a}$
• C. ln k vs 1/T
• D. ln k $vs - E_{a}/R$

Answer 1

Answer: (C)

ln k vs 1/T

Answer 2

The plot of ln k vs 1/T gives a straight line according to the equation,

ln $k = - \frac{E_{a}}{RT} + \ln A$
