Chemistry - Chemical Equilibrium Question with Solution | TestHub

Key Idea The reaction for which the number of moles of gaseous products $(n_{\mathrm{p}}$ ) is not equal to the number of moles of gaseous reactants $\left({\mathbf{n}}_{\mathrm{R}}\right)$, has different value of ${\mathrm{K}}_{\mathrm{c}}$ and ${\mathrm{K}}_{\mathrm{p}}$. (a) ${\mathbf{n}}_{\mathrm{P}}={\mathbf{n}}_{\mathrm{R}}=2$, thus, ${\mathrm{K}}_{\mathrm{p}}={\mathrm{K}}_{\mathrm{c}}$ (b) ${\mathrm{n}}_{\mathrm{P}}={\mathrm{n}}_{\mathrm{R}}=2$, thus, $K_{\mathrm{p}}={\mathrm{K}}_{\mathrm{c}}$ (c) ${\mathrm{n}}_{\mathrm{P}}={\mathrm{n}}_{\mathrm{R}}=2$, thus, ${\mathrm{K}}_{\mathrm{p}}={\mathrm{K}}_{\mathrm{c}}$ (d) $n_p=2,n_R=1$, thus, $K_p\ne K_c$
