Question

The reaction, N2 (g) + 3H2 (g) à2NH3 (g), is the formation of ammonia. What occurs as the reaction proceeds?

a precipitate is formed

light and heat are given off

a new odor is given off

the solution bubbles

Answer 1

this is gas phase reaction as result a precipitate is not formed and the solution bubbles is not given off. This is exothermic reaction and heat is given off but light is not given off.
Correct answer - a new odor is given off – N2 and H2 don’t have a odors, but NH3 has.
