We need to minimum buffering capacity is required so that the pH value of the samples analyzed does not have any influence on the system, 
What would happen if we used the higher buffering concentration
a) more electric power is applied, resulting in higher heat development. 
b) less electric power for less time  is applied, resulting in very high  heat development
c) higher buffering concentration need more electric power resulting increases in the temperature will increase the mobility and rate of migration of ions.
d) using the higher buffering concentration shows no affect at all

N2 combines with hydrogen to form ammonia under elevated temperature (about 200°C) and high pressure (about 200 atmospheres) and in the presence of a metal catalyst (usually iron). The extreme conditions are required to overcome the high activation energy of the reaction. This nitrogen fixation reaction, called
