Question
Constants I Periodic Table Part A The reaction 2 SO2(g) + 02 g)--2SOSg) has an eqib ium constant of 6 23 x 104 at 450 C. If the initial concentrations are [SO2 =0.230 M [O2 :0113 M and[SO- 15.3 M, which of the following statements is true? 0 The system is not at equilibrium and will shift to the left to estabish equilbrium. The system is at equilbrium and will not shift in either direction. O Cannot be predicted O The system is not at equilibrium and will shit to the right to establish equilibrium.

2SO2(g) + O2(g) --> 2SO3(g)
According to law of equilibrium, equilibrium constant, K = [SO3]2/[O2]1x[SO2]2
Q, (reaction quotient)= 15.32/.113x.2302 = 234.09/5.97= 39.21 , but K given is 6.23x104 which is more than calcuted value. So, K > Q
It means that reaction system is not in equilibrium and will shift to right direction.
