Consider the system
$$
\mathrm{A}(g)+2 \mathrm{~B}(g)+\mathrm{C}(s) \rightleftharpoons 2 \mathrm{D}(g)
$$
at $25^{\circ} \mathrm{C}$. At zero time, only $\mathrm{A}, \mathrm{B},$ and $\mathrm{C}$ are present. The reaction reaches equilibrium 10 min after the reaction is initiated. Partial pressures of $\mathrm{A}, \mathrm{B},$ and $\mathrm{D}$ are written as $P_{\mathrm{A}}, P_{\mathrm{B}},$ and $P_{\mathrm{D}}$
Answer the questions below, using LT (for is less than), GT (for is greater than), EQ (for is equal to), or MI (for more information required).
(a) $P_{\mathrm{D}}$ at $11 \mathrm{~min}$
$$
P_{\mathrm{D}} \text { at } 12 \mathrm{~min}
$$
(b) $P_{\mathrm{A}}$ at $5 \mathrm{~min} \longrightarrow P_{\mathrm{A}}$ at $7 \mathrm{~min}$.
(c) $K$ for the forward reaction reaction.
(d) At equilibrium, $K \longrightarrow$
(e) After the system is at equilibrium, more of gas $\mathrm{B}$ is added. After the system returns to equilibrium, $K$ before the addition of $\mathrm{B} \longrightarrow \mathrm{K}$ after the addition of $\mathrm{B}$.
(f) The same reaction is initiated, this time with a catalyst. $K$ for the system without a catalyst $K$ for the system with a catalyst.
(g) $K$ for the formation of one mole of $\mathrm{D}$ $K$ for the formation of two moles of $\mathrm{D}$.
(h) The temperature of the system is increased to $35^{\circ} \mathrm{C} . P_{\mathrm{B}}$ at equilibrium at $25^{\circ} \mathrm{C}$ $P_{\mathrm{B}}$ at equilibrium at $35^{\circ} \mathrm{C}$.
(i) Ten more grams of $\mathrm{C}$ are added to the system. $P_{\mathrm{B}}$ before the addition of $\mathrm{C} \longrightarrow P_{\mathrm{B}}$ after the addition of $\mathrm{C}$.
