Faraday

Explanation:

Faraday's laws of electrolysis, in chemistry, two quantitative laws used to express magnitudes of electrolytic effects, first described by the English scientist Michael Faraday in 1833.

Law of electrolysis was given by Faraday.

He discovered that,the amount of chemical change or decomposition is exactly proportional to the quantity of electricity that passes in solution,

the equation that correctly represent the reaction for formation of ammonia is

n2+ 3h2 → 2nh3 (answer d)

1 mole of nitrogen gas (n2) react with 3 moles of hydrogen gas (h2) to form 2 moles of ammonia ( nh3). this is in a process known as haber process were iron is used as a catalyst and reaction take place that a higher temperature and pressure. the process is exothermic hence energy is released.
