For the reaction CO(g)+(1 / 2) O_2(~g)=CO_2(~g), K_ p / K_ c is

For the reaction CO(g)+(1/2)O2( g)=CO2( g),Kp/Kc\mathrm{CO}(\mathrm{g})+(1 / 2) \mathrm{O}_2(\mathrm{~g})=\mathrm{CO}_2(\mathrm{~g}), \mathrm{K}_{\mathrm{p}} / \mathrm{K}_{\mathrm{c}} is

Options

  1. ART\mathrm{RT}
  2. B(RT)−1(\mathrm{RT})^{-1}
  3. C(RT)−1/2(R T)^{-1 / 2}
  4. D(RT)1/2(R T)^{1 / 2}

Correct answer

C. (RT)−1/2(R T)^{-1 / 2}

Step-by-step solution

Kp=Kc(RT)Δn;Δn=1−(1+12)=1−32=−12\mathrm{K}_{\mathrm{p}}=\mathrm{K}_{\mathrm{c}}(\mathrm{RT})^{\Delta n} ; \Delta \mathrm{n}=1-\left(1+\frac{1}{2}\right)=1-\frac{3}{2}=-\frac{1}{2} ∴KpKc=(RT)−1/2\therefore \frac{\mathrm{K}_{\mathrm{p}}}{\mathrm{K}_{\mathrm{c}}}=(\mathrm{RT})^{-1 / 2}
