Q64 · Chemistry

For an elementary chemical reaction, the Arrhenius plot is given below.

If the energy of activation is 6.64 kJ mol−1^{-1} and R = 8.3 J K−1^{-1} mol−1^{-1}, the temperature at which the rate constant becomes e2e^2 min−1^{-1}, is

The figure, described in words

Arrhenius plot: ln k (y-axis, 0-8) vs 1/T, straight line with negative slope and intercept 6 on the ln k axis.
