Chapter 17, Problem 59E

The rate constant for the decomposition of acetaldehyde, CH₃CHO, to methane, CH₄, and carbon monoxide, CO, in the gas phase is $1.1\times {10}^{-2}{\text{L mol}}^{\text{-}1}{s}^{\text{-}1}$ at 703 K and 4.95 L ${\text{mol}}^{\text{-1}}{\text{’ s}}^{\text{-1}}$ at 865 K. Determine the activation energy for this decomposition.
