69. Decomposition rate constant of acetone dicarboxylic acid
CO(CH2COOH)2 = CO(CH3)2 2CO2
at 273 K it is 4.1*10-5 s-1, and at 313 K it is 9.6*10-5 s-1. Determine the activation energy of this reaction. Answer: Eact = 15090 J / mol.

Activation energy of the phosgene decomposition reaction
COCI2 = CO Cl2
equal to 210 * 103 J / mol. Which of these 2 reactions under equal conditions will go faster and why?
Give a graph of energy change during a chemical reaction for an exothermic process. Show on the graph the segments corresponding to the activation energy of the direct reaction and the thermal effect of the reaction.
