Question

1 What volume of ammonia, in dm3, can be made from 30 dm3 of nitrogen and 60 dm of
hydrogen?
Assume that all volumes are measured at the same temperature and pressure and that
the reaction goes to completion according to the equation:
N2(g) + 3H2(g) → 2NH3(g)
A. 40
B. 60
C. 90
D. 180

Answer 1

Answer:

a

Explanation:

first find the limiting reagent

that is,

hydrogen because 3h2 requires 1n2

so

60dm3 will require 20dm3

and we have it in excess of 20dm3

so

N2 is the limiting reagent

hence , it can be said that we can 40dm3 of ammonia as 3dm3 of h2 will form 2dm3 of nh3
