Options

  1. A0.036
  2. B0.45
  3. C0.54
  4. D0.675

Correct answer

D. 0.675

Step-by-step solution

One mole of SO_3 was placed in a vessel of 1 ~L capacity at a certain temperature and the following equilibrium was
K_c=[SO2]2[O2][SO3]2=(0.6)2(0.3)(0.4)2=\frac{\left[\mathrm{SO}_2\right]^2\left[\mathrm{O}_2\right]}{\left[\mathrm{SO}_3\right]^2}=\frac{(0.6)^2(0.3)}{(0.4)^2}=0.675
