The reaction between ethanol and semicarbazide is shown below:
\(CH3 − CH = O + H2N − NH − C(= O) − NH2− > CH3 − CH = N − NH − C(= O) − NH2\)
The compound contains three nitrogen atoms
What will be the equilibrium constant of the given reaction carried out in a \(5 \,L\) vessel and having equilibrium amounts of \(A_2\) and \(A\) as \(0.5\) mole and \(2 \times 10^{-6}\) mole respectively?
The reaction : \(A_2 \rightleftharpoons 2A\)
