Dinitrogen (N2) and dioxygen (O2) are the main constituents of air but they do not react with each other to form oxides of nitrogen because
  • a)
    The reaction requires initiation by a catalyst
  • b)
    oxides of nitrogen are unstable
  • c)
    The reaction is endothermic and requires very high temperature
  • d)
    The stoichiometry of N2 and O2 in air is not ideal for the reaction to take place
Correct answer is option 'B'. Can you explain this answer?
Verified Answer
Dinitrogen (N2) and dioxygen (O2) are the main constituents of air but...
N2 and O2 are main constituents of air but they do not react with each other because N2 forms Pπ−Pπ bond which is stronger. So, to break that bond high energy is needed. So, it requires very high temperature.
