Chemistry - Thermodynamics - I Question with Solution | TestHub

Kirchoff's Equation-
$\Delta {\mathrm{H}}_{\mathrm{T}}=\Delta {\mathrm{H}}^{\circ }+\underset{298}{\overset{\mathrm{T}}{\int }}{\left(\Delta \mathrm{Cp}\right)}_{\mathrm{reac}}\mathrm{dT}$
$\Delta {\text{H}}_{\text{reac}}$ is dependent on temperature.
$\text{K}=\frac{\left[{\text{CO}}_2\right]\times 1}{1}$  as solids are treated at unit activity. $\mathrm{K}$ is independent of initial amount of ${\mathrm{CaCO}}_3$.
 $K_p=P_{C{O}_2}\left(g\right)$at a given temperature ${\mathrm{K}}_{\mathrm{p}}$ depends only on temperature.
$\Delta \text{H}={\text{E}}_{\text{a}\left(\text{for}\right)}-{\text{E}}_{\text{b}\left(\text{back}\right)}$ 

A catalyst lowers only the activation energies & $\Delta {\text{H}}_{\text{react}}$ is independent of catalyst.
