Sapling (5/6) #18
For #18, I have to find the equilibrium constant K using the deltaG(f) equation. I followed all of the instructions where you find the deltaG and then use the equation deltaG = -RT*ln(K). However, I keep getting the wrong answer. Can someone help me with the steps to solve this problem?
Re: Sapling (5/6) #18
One thing that stumped me was that I kept forgetting to convert from kJ to J when calculating for the equilibrium constant. Maybe that could be a place where you miscalculated?

So for reaction 1
After that you substitute into the equation so we now solve for K
so
Follow the same process for the other reaction

1. Find G (convert from joules to moles)
ΔG∘r=ΣnΔG∘f(products)−ΣnΔG∘f(reactants)
2. Find K from G
ΔG∘r=−RTln(K)
ΔG∘r=ΣnΔG∘f(products)−ΣnΔG∘f(reactants)
2. Find K from G
ΔG∘r=−RTln(K)
Return to “Van't Hoff Equation”
