Consider the four plots for the chemical equilibrium, $CaCO_{3} (s) ⇌ CaO (s) + CO_{2} (g)$ . Which one of them can be used to determine $Δ H_{r}^{o}$ ?

Options:

Answer:

Solution:

$CaCO_{3} (s) ⇌ CaO (s) + CO_{2} (g)$ .

$K_{p} = P_{C O_{2}}$ ; $K = A e^{- \frac{Δ H _{r}^{\circ}}{RT}}$ .

$lo g K_{p} = lo g A - \frac{Δ H _{r}^{\circ}}{2.303 RT}$

$lo g (P_{C O_{2}}) = lo g A - \frac{1}{T} \times \frac{Δ H _{r}^{\circ}}{2.303 R}$

$y = c + m x$ .
