The heat of vaporization is is 69kJ/mol at 646degrees Celsius. The reaction is Rb(l) to Rb(g), the gas is at 1atm at 646degrees Celsius.

I need Suniverse, Ssurroundings, deltaS, and delta G.

dS = dHvap/Tb
dS(sys) + dS(surr) = 0(revesible)
dS(surr) = -dS(sys)
dG = dH + TdS
check its value at equilibrium

So...
69/919=.075081
universe=0

could you plug it in? I got a few you like this, but would like to see one done and see if I can do the rest myself. I am still somewhat confused
