MCQ
For the reaction $CO(g) + 2{H_2}(g)$ $\rightleftharpoons$ $C{H_3}OH(g)$, true condition is
  • A
    ${K_p} = {K_c}$
  • B
    ${K_p} > {K_c}$
  • ${K_p} < {K_c}$
  • D
    ${K_c} = 0$ but ${K_p} \ne 0$

Answer

Correct option: C.
${K_p} < {K_c}$
(c) When ${n_r} > {n_p}$ then ${K_p} < {K_c}$

where ${n_r}$ $=$ no. of moles of reactant

${n_p}$ $=$ no. of moles of product.

Redox reactions play a pivotal role in chemistry and biology. The values of standard redox potential ( $\mathrm{E}^{\circ}$ ) of two half-cell reactions decide which way the reaction is expected to proceed. A simple example is a Daniel cell in which zinc goes into solution and copper gets deposited. Given below are a set of half-cell reactions (acidic medium) along with their $E^{\circ}$ ($V$ with respect to normal hydrogen electrode) values. 

$\mathrm{I}_2+2 \mathrm{e}^{-} \rightarrow 2 \mathrm{I}\ \ \   \mathrm{E}^{\circ}=0.54 $

$\mathrm{Cl}_2+2 \mathrm{e}^{-} \rightarrow 2 \mathrm{Cl}^{-} \ \ \  \mathrm{E}^{\circ}=1.36 $

$\mathrm{Mn}^{3+}+\mathrm{e}^{-} \rightarrow \mathrm{Mn}^{2+} \ \ \  \mathrm{E}^{\circ}=1.50 $

$\mathrm{Fe}^{3+}+\mathrm{e}^{-} \rightarrow \mathrm{Fe}^{2+} \ \ \  \mathrm{E}^{\circ}=0.77 $

$\mathrm{O}_2+4 \mathrm{H}^{+}+4 \mathrm{e}^{-} \rightarrow 2 \mathrm{H}_2 \mathrm{O} \ \ \  \mathrm{E}^{\circ}=1.23$

$2.$ While $\mathrm{Fe}^{3+}$ is stable, $\mathrm{Mn}^{3+}$ is not stable in acid solution because

$(A)$ $\mathrm{O}_2$ oxidises $\mathrm{Mn}^{2+}$ to $\mathrm{Mn}^{3+}$

$(B)$ $\mathrm{O}_2$ oxidises both $\mathrm{Mn}^{2+}$ and $\mathrm{Fe}^{2+}$ to $\mathrm{Fe}^{3+}$

$(C)$ $\mathrm{Fe}^{3+}$ oxidizes $\mathrm{H}_2 \mathrm{O}$ to $\mathrm{O}_2$
