NEET Chemistry — Equilibrium

For \( \ce{2A(g) + B(g) <=> 2C(g)} \), \( K_p = 16 \) at 500 K. If initial pressures are \( P_{\ce{A}} = 2 \, \text{atm} \), \( P_{\ce{B}} = 1 \, \text{atm} \), what is \( P_{\ce{C}} \) at equilibrium?

For the reaction \( \ce{CO(g) + Cl2(g) <=> COCl2(g)} \), if \( K_c = 9 \) and initial concentrations are \( [\ce{CO}] = 0.3 \, \text{M} \), \( [\ce{Cl2}] = 0.3 \, \text{M} \), what is \( [\ce{COCl2}] \) at equilibrium?

The \( K_w \) of water at 373 K is \( 1.0 \times 10^{-12} \). What is the pH of pure water at this temperature?

For \( \ce{2NO(g) + Cl2(g) <=> 2NOCl(g)} \), \( K_p = 9 \) at 500 K. If initial pressures are \( P_{\ce{NO}} = 1 \, \text{atm} \), \( P_{\ce{Cl2}} = 0.5 \, \text{atm} \), what is \( P_{\ce{NOCl}} \) at equilibrium?

For \( \ce{2A(g) + B(g) <=> 3C(g)} \), \( K_p = 9 \) at 500 K. If \( P_{\ce{A}} = 0.5 \, \text{atm} \), \( P_{\ce{B}} = 0.5 \, \text{atm} \), and \( P_{\ce{C}} = 1.5 \, \text{atm} \) at equilibrium, what happens if pressure is doubled?
