Carbon and energy yields in prebiotic syntheses using atmospheres containing CH4, CO and CO2.


Yields based on carbon are usually reported in prebiotic experiments, while energy yields (moles cal-1) are more useful in estimating the yields of products that would have been obtained from the primitive atmosphere of the earth. Energy yields for the synthesis of HCN and H2CO from a spark discharge were determined for various mixtures of CH4, CO, CO2, H2, H2O, N2 and NH3. The maximum yields of HCN and H2CO from CH4, CO, and CO2 as carbon sources are about 4 X 10(-8) moles cal-1.
