### Lyndon's Week 9 WS #7 Clarification Question

**Sat Dec 09, 2017 3:47 pm**Number 7 asks: From number 1, SO

I have 2 questions regarding questions similar to this one:

1) Suppose everything in the question was the same except the K

2) Suppose everything in the question was the same except you were given the concentration of SO

_{3(g)}<-->SO_{2(g)}+O_{2(g)}. The K_{c}of the reverse reaction is 5.66*10^(-10). What are the equilibrium concentrations of all the products and reactants if you first introduce a 0.522M sample of SO_{2}with a 0.633M sample of O_{2}?I have 2 questions regarding questions similar to this one:

1) Suppose everything in the question was the same except the K

_{c}of the forward reaction was given. You would have to take the inverse of that K_{c}to get the K_{c}of the reverse reaction and then solve for x, right?2) Suppose everything in the question was the same except you were given the concentration of SO

_{3}instead of the concentrations of SO_{2}and O_{2}. You would have to take the inverse of the K_{c}given to get the K_{c}of the forward reaction because in this new scenario the forward reaction would be favored, right?
