Relative is the operational word here Robin. I misunderstood your description of the 2 billion years half life of He2. The decay of He2 into H2 should be much, much quicker than that! Just an off the cuff estimate, it should be less than a second. We can obtain a closer guess if you wish, but the decay would be far shorter than the 2 billion years number.
Your suggestion about the percentage of H that reacts per second begs a question. Would it not be possible for the core temperature to adjust downward to accommodate the rate that exists? I have always wondered why stars did not in fact explode immediately upon first ignition unless some form of negative feedback controls the rate of energy production. One would think that the region that first ignited would generate a large amount of energy that would raise the temperature in the immediate area. A higher temperature would suggest that more fusion would occur leading to ever higher temperature until boom.

Then may I suggest that you work out the percentage of H in the solar core that ctually reacts per second. If the reaction were fast, stars wouldn't exist. hey would go nova immediately after ignition. Regards, Robin van Spaandonk http://rvanspaa.freehostia.com/project.html
