MCQ
For the equilibrium

$SO_2Cl_2(g) \rightleftharpoons  SO_2(g) + Cl_2(g)$ , what is the temperature at which $\frac{{{K_p}(atm)}}{{{K_c}(M)\,}} = \frac{1}{3}$ ? ......$K$

  • A
    $0.027$
  • B
    $0.36$
  • C
    $36.54$
  • $4.06$

Answer

Correct option: D.
$4.06$
d
$\Delta \mathrm{n}=1$

$\frac{\mathrm{K}_{\mathrm{p}}}{\mathrm{K}_{\mathrm{c}}}=(\mathrm{RT})^{\Delta \mathrm{n}}=0.0821 \times \mathrm{T}$

$\frac{1}{3}=0.0821 \times \mathrm{T}$

$\frac{1}{3 \times 0.0821}=\mathrm{T}$

$4.06\, \mathrm{K}=\mathrm{T}$
