See more at energy Examples of activation energyactivation energy When the bonds are in series, the selectin bond of lower activationenergy will fail first at low loading rates (below the crossover point). The activationenergy will be supposed much larger than the thermal energy. We may consider the partially formed helix as an intermediate that gives an activationenergy for the helix-formation process. The graphite moderates the neutrons below activationenergy levels. A physical reason for this is that as the activationenergy increases, the induction time and corresponding induction length increase exponentially. Our results suggest that as the activationenergy is increased even further than we have shown, additional highfrequency instabilities appear. Note that once an unstable mode is present, its growth rate changes with increasing activationenergy, but its frequency is nearly constant. The effect of on the rate constant thus is very small compared to the enormous increases in rate that enzymes can achieve by reducing the activationenergy. Semiconductor iron sulphide minerals are readily doped and would have provided an adaptable source of holes and electrons for low activationenergy redox chemistry. This means that although two proteins may bind at a similar rate, if they have a different activationenergy, there must be two different kinetics barriers that are operative. In contrast, the ratio of helix formation and break-up rates depends on the free energy difference between the two end configurations, and not on the activationenergy. Chilkoti et al. (1995) confirmed experimentally the importance of the activationenergy in unbinding. There also exist cases where the ignition factor is not the activationenergy.

Not only was the activationenergy for these materials much lower, but they could also undergo much larger deformations.

With the proper activationenergy for crystallization it is possible to have fast crystallization at programming conditions while having very slow crystallization at normal conditions.
