Equilibrium Improbable Reactions Worksheet

Predict the probability of the following reactions at 25oC. If a reaction is improbable, at what temperature might it become probable?

a)   C4H10(g) -------> 4 C(s) + 5 H2(g)

b)   2 Fe(s) + ½N2(g) ------> Fe2N(s)    ΔH = -3.76 kJ/mole  ΔS = -14.65 J/mole

c)   HCl(g) + H2O(l) -------> H3O+(aq) + Cl-(aq)

d)   N2(g) + 2 O2(g) ------> 2 NO2

e)   2 C(s) + O2(g) ----> 2 CO(g)
