Okay thanks for clarifying. That makes complete sense. I was thinking that ΔS should be the same either way you calculate it. Okay so I looked at the problem again and apparently it didn't include and ΔH so I am still unclear on how to solve it. It says at STP so 298K and 1 atm.
The way I...
Awesome, thanks for the reply. So now I understand that one can solve for ΔS using the formula for Gibbs Energy. I'm wondering why you can't solve for ΔS just by using Sigma(Sproducts)-Sigma(Sreactants, in this case? Although in the context of this problem ΔHrxn and T are given so it makes...
By the way run was supposed to be rxn in the last sentence of attempt. The way I attempted to solve the problem uses the equation DeltaSrxn= Sum(S products)- Sum(S reactants). Then I am assuming that Delta S surroundings= -Delta S rxn, but that doesn't seem to work here The chemistry class...
The question asks to solve for delta S surroundings at 298K when 2.49 moles of H2S (g) react.
reaction:
2H2S (g) + 3O2 (g)= 2H2O (g) + 2SO2 (g)
My problem is that I don't know how to calculate delta S surroundings. So to solve the problem I'm making the assumption that -Delta S surroundings =...
