I am trying to understand how to balance this equation.
We were given the following data to solve for delta G (standard).
S(s) + 3/2 O2(g)--------->SO3(g) delta G standard = -371kJ
2SO2(g)+ O2(g)--------->2SO3(g) delta G standard = -142kJ
Now calculate delta G standard for the reaction.
delta G standard = delta H standard - T delta S standard
Please explain in detail how to balance these two equations together and add them. I do not understand where they are getting the 1/2 (142 kJ0), and why on the second number we have no coefficient on -371 kJ then we end up with 71kJ - 371 kJ = -300? Could you please explain?© BrainMass Inc. brainmass.com September 19, 2018, 8:48 am ad1c9bdddf - https://brainmass.com/chemistry/energetics-and-thermodynamics/calculating-delta-39255
What you want to do is to use these two equations to get a new equation:
S(s) + O2(g) -----> SO2(g)
So you need to get rid ...
