12. On ellipse 1, place an " over the location of a focus. Now place an "X" on the orbit where the planet's orbital velocity (speed) would be greatest. On the lines below, explain how you know where to place your "X"

Amixture initially contains a, b, and c in the following concentrations: [a] = 0.300 m , [b] = 1.05 m , and [c] = 0.550 m . the following reaction occurs and equilibrium is established: a+2b⇌c at equilibrium, [a] = 0.140 m and [c] = 0.710 m . calculate the value of the equilibrium constant, kc.
