Official previous-year question

Held on 30 Apr 2005 · Verified 9 Jul 2026.

Options

A
$\mathrm{K}_2=1 / \mathrm{K}_1{ }^2$
B
$\mathrm{K}_2=\mathrm{K}_1{ }^2$
C
$\mathrm{K}_2=1 / \mathrm{K}_1$
D
$\mathrm{K}_2=\mathrm{K}_1 / 2$

Did you get this right?

Solution

$\mathrm{K}_1=\frac{p_{\mathrm{NO} 2}}{p_{\mathrm{NO}} \cdot\left(\mathrm{p}_{\mathrm{O} 2}\right)^{1 / 2}}$ $\mathrm{K}_2=\frac{\left(p_{\mathrm{NO}}\right)^2 \cdot p_{\mathrm{O} 2}}{\left(\mathrm{p}_{\mathrm{NO} 2}\right)^2}$ takin square root on both sides in eq. 2. $\begin{aligned} & \Rightarrow \sqrt{\mathrm{K}_2}=\frac{p_{\mathrm{NO}} \cdot\left(p_{\mathrm{O} 2}\right)^{1 / 2}}{p_{\mathrm{NO} 2}} \\ & \Rightarrow \sqrt{\mathrm{K}_2}=\frac{1}{\mathrm{~K}_1} \Rightarrow \mathrm{K}_2=\frac{1}{\mathrm{~K}_1^2} \end{aligned}$
