In Which of the following changes, nitrogen is reduced
Correct answer: B. N2 to NH3
- A. NH3 to NO
- B. N2 to NH3
- C. NH3 to NO3
- D. N-3 to N2
Explanation
The correct explanation is that option (b) represents the reduction of nitrogen. In the reaction N2 to NH3, nitrogen goes from an oxidation state of 0 in N2 to -3 in NH3, indicating a reduction (gain of electrons).

About Reaction Kinetics
Reaction kinetics relates reaction rate to concentration, temperature, surface area and catalysts. Questions cover rate laws, reaction order, rate constants, activation energy and the activated complex, including how a catalyst lowers the activation energy without changing the overall energy change or equilibrium position.
