In the reaction, `N_(2)+ 3" H"_(2) rarr 2 NH_(3),` the ratio of
volumes of nitrogen, hydrogen and ammonia is
1 : 3 : 2 These ratio illustrate the law of

Options

A. Law of multiple proportion
B. Avogadro's Law
C. Law of conservation of volume
D. Gay Lussac's law of combing volumes of gases.

Answer

D

Explanation

`N_(2(g))+3H_(2(g)) to 2NH _(3(g))`
1 volume of nitrogen gas reacts with 3 volumes of hydrogen gas to produce 2 volumes of ammonia gas. Hence according to Gay Lussac's law of combining volume of gases the ratio of `N_2:H_2 : : NH_3` is 1 : 3 : : 2
