“It is said that lightning is a boom to plants”. Justify the state

1.	“It is said that lightning is a boom to plants”. Justify the statement?
Answer» During lightening the triple bond in nitrogen breaks and combine with the atmospheric oxygen to form nitric oxide (NO) N₂ + O₂ → 2NO Nitric oxide thus formed further combines with more amount of oxygen to form nitrogen dioxide (NO₂) 2NO + O₂ → 2NO₂ Nitrogen dioxide dissolves in rainwater in the presence of oxygen and reaches the soil as nitric acid (HNO₃) 4NO₂ + 2H₂O + O₂ → 4HNO₃ Nitric acid reacts with the minerals in the soil to form nitrate salts which is absorbed by the plants. So it is said that lightning is a boom to plants.

Answer»

During lightening the triple bond in nitrogen breaks and combine with the atmospheric oxygen to form nitric oxide (NO)

N₂ + O₂ → 2NO

Nitric oxide thus formed further combines with more amount of oxygen to form nitrogen dioxide (NO₂)

2NO + O₂ → 2NO₂

Nitrogen dioxide dissolves in rainwater in the presence of oxygen and reaches the soil as nitric acid (HNO₃)

4NO₂ + 2H₂O + O₂ → 4HNO₃

Nitric acid reacts with the minerals in the soil to form nitrate salts which is absorbed by the plants. So it is said that lightning is a boom to plants.
