WebAcetaldehyde (ethanal) is an aldehyde that is highly reactive and toxic. Acetaldehyde causes damage at the cellular and genomic levels. ... The balance between diacetyl, which is the most aromatic, and the other products is very dependent on the pH of the medium, temperature and redox potential, probably much more than on the strain itself. The ... WebThe rate constant for the decomposition of acetaldehyde, CH 3 CHO, to methane, CH 4, and carbon monoxide, CO, in the gas phase is 1.1 × × 10 −2 L mol −1 s −1 at 703 K and 4.95 L mol −1 s −1 at 865 K. Determine the activation energy for this decomposition.
