When the partial pressure is measured in atmosphere, the value of \( K_p \) at \( 500^\circ\text{C} \) is \( 1.44 \times 10^{-5} \). 
The value of \( K_c \) when the concentration is expressed in \( \text{mol L}^{-1} \) is:
\(\underline{\hspace{3cm}}\).

For the following gaseous reversible reaction: 
\( 3 \, \text{A}_{(g)} + \text{B}_{(g)} \rightleftharpoons \, \text{A}_3 \text{B}_{(g)} \) 
(\( \Delta H = -q \, \text{kJ} \)), the amount of product \( \text{A}_3 \text{B}_{(g)} \) is affected by 
\(\underline{\hspace{3cm}}\).

For a reaction having three steps, the overall rate constant is \( K = \frac{k_1 k_3}{k_2} \). The values of \( E_{a1} \), \( E_{a2} \), and \( E_{a3} \) (activation energies stepwise) are 40, 50, and 60 kJ mol\(^{-1}\) respectively. 
Then the overall \( E_a \) (activation energy) of the reaction is 
\(\underline{\hspace{3cm}}\).
