Question

Hydrazine, n2h4, is widely used as a rocket fuel because it reacts with oxygen as shown, producing ‘environmentally friendly' gases. n2h4(l) + o2(g) → n2(g) + 2h2o(g) ∆h = –534kj mol–1 despite its use as a rocket fuel, hydrazine does not spontaneously burn in oxygen. why does hydrazine not burn spontaneously?

Answer 1

Hydrazine is a gaseous compound if Nitrogen.

It has a very high activation energy from other compounds.

A spontaneous reaction requires less activation energy.

Due to the high activation energy of hydrazine, it does not burn spontaneously in oxygen.

However this does not mean that it does not react with oxygen, if adequate energy is applied enough to break the bonds, it reacts with oxygen.
