Question

10 Which of the following statements is FALSE
the chemical equation given below in which
nitrogen gas reacts with hydrogen gas to fom
ammonia gas assuming the reaction goes to
completion
N. + 3H2NH:
A The reaction of one mole of H, will produce
2/3 moles of NH
B. One mole of N, will produce two moles of
NH.
C. One molecule of nitrogen requires three
molecules of hydrogen for complete
reaction
Dy The reaction of three moles of hydrogen gas
will produce 17 g of ammonia
with solution ans please.​

Answer 1

Answer:

D-false

solution:

N2 + 3H2 --------> 2NH3

3moles H2 2moles of ammonia

1 mole of ammonia =17 g

2 mole of ammonia = 34 g

Ans. 3 moles of H2 produce 34 g of ammonia.

Answer 2

Answer:

The reaction of three moles of hydrogen gas that will produce 17 g of ammonia is a false statement i.e.(D).

Explanation:

The reaction proceeds as follows,

$N_2+3H_2\rightarrow 2NH_3$      (1)

Where,

N₂=nitrogen gas

H₂=hydrogen gas

NH₃=ammonia

From equation (1) we can draw the following conclusions:-

• We can see that 2 moles of H₂ produce 3 moles of NH₃.So, 1 mole of H₂ produces,

                        $1\ mole\ H_2=\frac{2}{3} \ moles\ of \ NH_3$    (2)

• One mole of nitrogen gas(N₂) produces two moles of ammonia(NH₃).
• One molecule of nitrogen requires three molecules of hydrogen for a complete reaction.
• The reaction of 3 moles of hydrogen gas produces 34 g of ammonia as there is the production of 2 moles of ammonia.

Hence, the reaction of three moles of hydrogen gas that will produce 17 g of ammonia is a false statement i.e.(D).
