Knallgas reaction

Such inorganically released hydrogen would have been available to be exploited by microbial life. Some archaea and bacteria use the knallgas reaction ... 

In certain aerobic organisms, such as hydrogenomonas, H2 and O2 are caused to react (but not directly) according to the Knallgas reaction ... 

Now the affinity A of the reaction 2H2 + 02 -> 2H20, in which the reactants are gaseous and the resultant a liquid, e the affinity of the actual process occurring in the Knallgas cell, is given by—... 

This can be calculated numencally from equation (9c) given above We can thus calculate the affinity of the reaction m the Knallgas cell Now A refers to the formation of 2 moles of water To foim 2 moles of water electncally requires four faradays, and hence A = 4E, where E is the electromotive force of the cell Calculating Kp as above... 

Fiq. 3-21. Ratio of peak reaction pressure to initial mixture pressure vs. composition of Knallgas saturated with water vapor at 100°C. Tube diameter = 0.957 in., spark ignition energy = 180 millijoules.
