  1. Question 1

    Q1. During a thunderstorm, the high temperature of a lightning bolt provides the activation energy for atmospheric gases to react. What is the first oxide of nitrogen formed?

    • A) Nitrogen dioxide (NO2)
    • B) Dinitrogen oxide (N2O)
    • C) Nitric oxide (NO)
    • D) Dinitrogen pentoxide (N2O5)

    Answer: Nitric oxide (NO)

    Explanation: Nitrogen and oxygen combine only at high temperatures (approx. 3000C) produced by lightning or electric arcs to form Nitric oxide (NO).
