JEE Mains · Chemistry · STD 12 - 3. Chemical kinetics

પ્રક્રિયા \(2 \mathrm{H}_{2}(\mathrm{g})+2 \mathrm{NO}(\mathrm{g}) \rightarrow \mathrm{N}_{2}(\mathrm{g})+2 \mathrm{H}_{2} \mathrm{O}(\mathrm{g})\) માટે અવલોકન વેગ રજૂઆત, વેગ \(=\mathrm{k}_{\mathrm{f}}[\mathrm{NO}]^{2}\left[\mathrm{H}_{2}\right]\) છે. તો પ્રતિગામી પ્રક્રિયા માટે વેગ રજૂઆત જણાવો.

  1. A \(\mathrm{k}_{\mathrm{b}}\left[\mathrm{N}_{2}\right]\left[\mathrm{H}_{2} \mathrm{O}\right]^{2} /[\mathrm{NO}]\)
  2. B \(\mathrm{k}_{\mathrm{b}}\left[\mathrm{N}_{2}\right]\left[\mathrm{H}_{2} \mathrm{O}\right]\)
  3. C \(\mathrm{k}_{\mathrm{b}}\left[\mathrm{N}_{2}\right]\left[\mathrm{H}_{2} \mathrm{O}\right]^{2}\)
  4. D \(\mathrm{k}_{\mathrm{b}}\left[\mathrm{N}_{2}\right]\left[\mathrm{H}_{2} \mathrm{O}\right]^{2} /\left[\mathrm{H}_{2}\right]\)

Answer & Solution

Correct Answer

(D) \(\mathrm{k}_{\mathrm{b}}\left[\mathrm{N}_{2}\right]\left[\mathrm{H}_{2} \mathrm{O}\right]^{2} /\left[\mathrm{H}_{2}\right]\)

Step-by-step Solution

Detailed explanation

\(\mathrm{K}_{\mathrm{eq}}=\frac{\mathrm{k}_{\mathrm{f}}}{\mathrm{k}_{\mathrm{b}}}=\frac{\left[\mathrm{N}_{2}\right]\left[\mathrm{H}_{2} \mathrm{O}\right]^{2}}{\left[\mathrm{H}_{2}\right]^{2}[\mathrm{NO}]^{2}}\) At equilibrium \(\mathrm{r}_{\mathrm{f}}=\mathrm{r}_{\mathrm{b}}\)…
