(K_p)/(K_c) for following reaction will be

KpKc\frac{K_p}{K_c}for following reaction will be

Options

  1. ARTR T
  2. B1RT\frac{1}{R T}
  3. C1RT\frac{1}{\sqrt{R T}}
  4. DRT2\frac{R T}{2}

Correct answer

C. 1RT\frac{1}{\sqrt{R T}}

Step-by-step solution

Δng=np−nr=1−32\Delta_{n_g}=n_p-n_r=1-\frac{3}{2} Δng=−12\Delta_{n_g}=\frac{-1}{2}. Hence Kp=Kc(RT)−1/2K_p=K_c(R T)^{-1 / 2} KpKc=1(RT)1/2=1RT\frac{K_p}{K_c}=\frac{1}{(R T)^{1 / 2}}=\frac{1}{\sqrt{R T}}
