What are the enthalpy, entropy, and free energy for the hydrogenation of ethene (C2H4) to ethane (C2H6) at 25 degrees. Is this a spontaneous process and how can you tell?

What do you need help with on this. I'm sure it isn't all of the problem.
Write the equation and balance it.
dHrxn = (n*dHf products)-(n*dHf reactants)
dSrxn = (n*dSo products)-(n*dSo reactants)
dGrxn = dHrxn -TdSrxn
Spontaneity is when dG is negative.
