| Abstract: | Using one-dimensional unsym. Eckart potential energy barrier, thermal reaction system of formaldehyde was studied. In addition, a series of rate constants and activation energies have been calculated at different thermal effects and the effect of unsymmetry of potential barrier on the results of calcns. has been discussed in detail. The results of calcns. are in agreement with experimental results. |
