Question

The rate constant for the decomposition of acetaldehyde, CH3CHO, to methane, CH4, and carbon monoxide, CO, in the gas phase is 1.59 ✕ 10−2 L/mol/s at 711 K and 3.63 L/mol/s at 855 K. Determine the activation energy (in kJ/mol) for this decomposition.

______ kJ/mo

Answer 1

Plug those numbers into the Arrhenius equation.
