List of top Chemistry Questions on Equilibrium Constant asked in AP EAPCET

At T(K) the $K_c$ for the reactions (I) and (II) are $2.4 \times 10^{30}$ and 1.4 respectively. What is the $K_c$ value for: $\frac{1}{2}N_2(g) + \frac{1}{2}O_2(g) + \frac{1}{2}Br_2(g) \rightleftharpoons NOBr(g)$?

At a given temperature T in a 10.0 L flask, 2.0 moles of N$_2$O$_4$(g) is heated. At equilibrium, 20% of N$_2$O$_4$(g) dissociates into NO$_2$(g). The value of K$_C$ for the reaction N$_2$O$_4$(g) $\rightleftharpoons$ 2NO$_2$(g) is:

For ammonia formation from constituent elements, the expression for \(K_c\) is

At \(500\,\text{K}\), for the reaction, \[ N_2(g)+3H_2(g)\rightleftharpoons 2NH_3(g), \] the \(K_p\) is \(0.036\,\text{atm}^{-2}\). What is its \(K_c\) in \(L^2\text{mol}^{-2}\)? \((R=0.082\,L\,\text{atm mol}^{-1}\text{K}^{-1})\)
