${\mathrm{K}}_{\mathrm{c}}$ for $\mathrm{A}+\mathrm{B}\rightleftharpoons \mathrm{C}+\mathrm{D}$ is $10$ at $25°\mathrm{C}$. If a container contains $1, 2, 3$ and $4 \mathrm{mol}$ of $\mathrm{A}, \mathrm{B}, \mathrm{C}$ and $\mathrm{D}$, respectively, at $25°\mathrm{C}$, the reaction shall

Which of the following curves represents a very rare standard reactivity at equilibrium?

Which of the curves given represents a standard reaction spontaneous in forward direction?

Which of the curves given represents a standard reaction for which ${\mathrm{\Delta G}}^0>0?$

Which of the curves given represent a standard reaction with $\mathrm{K}=1$?

The energy profile of the reaction, $\mathrm{A}+\mathrm{B}\rightleftharpoons \mathrm{C}$ is shown as,

The equilibrium constant for the said equilibrium

$\mathrm{NiO}$ is to be reduced to $\mathrm{Ni}$ in an industrial process by the use of the reaction $\mathrm{NiO} \left(\mathrm{s}\right)+\mathrm{CO} \left(\mathrm{g}\right)\rightleftharpoons \mathrm{Ni} \left(\mathrm{s}\right)+{\mathrm{CO}}_2 \left(\mathrm{g}\right)$

At $1600 \mathrm{K}$, the equilibrium constant for the reaction is $600$. If a $\mathrm{CO}$ pressure of $150 \mathrm{mm} \mathrm{Hg}$ is to be employed in the furnace and the total pressure never exceeds $760 \mathrm{mm} \mathrm{Hg},$ will the reduction occur?

Which of the following curves between $\log \mathrm{K}$ and $\frac{1}{\mathrm{T}}$ is correct for an endothermic reaction?
