WebThe pH for reactions which form imine compounds must be carefully controlled. The rate at which these imine compounds are formed is generally greatest near a pH of 5, and drops at higher and lower pH’s. At high pH there will not be enough acid to protonate the OH in the intermediate to allow for removal as H 2 O. At low pH most of the amine ... 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.
