Electronegativity differences. Because nitrogen is more electronegative than carbon, the pi molecular orbitals (the ones making the triple bond) of N2 are lower in energy than that of C2H2.
Explanation:
Easily put... They are different compounds with different preparations and stored energy. Acetylene is formed in the partial combustion of methane so it is unstable to begin with. Triple bonded nitrogen you can think of it as a lowest energy state. Energy goes into forming acetylene, energy is released when nitrogen triple bonds..
Hope it helps..!!
Ответ:
Molecules must collide with sufficient energy, known as the activation energy, so that chemical bonds can break. Molecules must collide with the proper orientation. A collision that meets these two criteria, and that results in a chemical reaction, is known as a successful collision or an effective collision.
