1 Is this reaction exoergic or endoergic? What energy does it require or give off? (Known as the Q value) Au( , d) Hg Au =  = He = Hg = d = 2 H = Q = MeV (Endo)

2 Q = MeV (Exo) Try this reaction - is it endo or exo, and how much? K(p, n) Ca K = p = H = Ca = n =

3 Q = MeV (Exo) Try this reaction - is it endo or exo, and how much? Ba(n,  ) Ba Ba = n = Ba =  = ??
