Question

2 litres of n2 and 2 litres of h2 on complete reaction would give how many litres of nh3 ?

Answer 1

Answer:1.32L of NH3

Explanation:

No.of moles of N2 = 2L/22.4L=0.089

No.of moles of H2 = 2L/22.4L = 0.089

N2 + 3H2 -> 2NH3

3mol H2 combine with 1 mol of N2

0.089mol of H2 combine with 1/3×0.089= 0.029 mol of N2

Hence, H2 acts as a limiting reagent.

Now, 3mol of H2 gives 2mol of NH3

0.089mol of H2 will give =(2/3)×(0.089)mol of NH3

= 0.059 mol of NH3

=0.059×22.4 = 1.32L
