At a given temperature, K_p = K_c for which of the following reactions?
NEET level
The unit of K_p for the reaction 2SO2(g) + O2(g) <=> 2SO3(g), when pressures are in atm, is
NEET level
The unit of K_c for the reaction N2O4(g) <=> 2NO2(g), with concentrations in mol L^-1, is
NEET level
For PCl5(g) <=> PCl3(g) + Cl2(g), K_c = 0.040 mol L^-1 at 500 K. Taking R = 0.0821 L atm mol^-1 K^-1, K_p (in atm) is approximately
NEET level
For 2NO(g) + O2(g) <=> 2NO2(g), K_c = 1.2x10^3 L mol^-1 at 300 K. Taking R = 0.0821 L atm mol^-1 K^-1, K_p in atm^-1 is approximately
NEET level
For N2O4(g) <=> 2NO2(g) at 298 K, K_c = 5.8x10^-3 mol L^-1. Using R = 0.0821 L atm mol^-1 K^-1, calculate K_p in atm, correct to two decimal...
