| Abstract: | The heat effect in the reduction of copper(II) by formaldehyde on palladium catalyst particles accompanied by hydrogen evolution
depends on the presence of deuterium in the system. In the case of 80% substitution of hydrogen in the system by deuterium
the heat effect increases 1·5 times. This fact can not be attributed only to the difference in the energies of the bonds of
hydrogen and deuterium in compounds participating in the reaction. |
