Determine the electrical work required to produce one mole of hydrogen in the electrolysis of liquid water at 298 k and 1 atm. the chemical reaction is-
h2o(l) = h2 (g) + 0.5 o2 (g)
data (at 298 k and 1 atm): delta h= 286 kj for this reaction, sh2o =70 j/k , sh2o= 131 j/k and so2= 205 j/k

Small amounts of matter are converted intolarge amounts of energy occurs in both fusion and fission reactions. they are nuclear reactions where a change in the identity or characteristics of an atomic nucleus results when it is bombarded with an energetic particle, as in fission, fusion, or radioactive decay.
