For the reaction, 2 SO2(g) + O2(g) == 2 SO3(g), at 450.0 K (Kelvin) the equilibrium constant, Kc, has a value of 4.62. A system was charged to give these initial concentrations, (SO3) = 0.254 M and (O2) = 0.00855 M, and (SO2) = 0.500 M. In which direction will it go?
A. to the right
B. to the left
C. it will remain at the same concentrations
D. not enough data to tell
I think that it will remain the same.
Is this correct?
You need to substitute into the Keq expression (called the reaction quotient when you put the INITIAL values in) and compare that with Kc. I don't think D is correct.
