At a certain temperature and total pressure of `10^5` Pa ,iodine vapour contains `40%` by volume of iodine atoms. Calaulate `K_p` for the equilibrium, `1_2(g)iff2I(g)`.

A sample of HI(g) is placed in a flask at a pressure of 0.2 atm. At equilibrium, the partial pressure of HI(g) is 0.04 atm. What is K_p for the equilibrium 2HI(g) iff H_2(g)+I_2(g)

Consider the following equilibrium in a closed container N_(2)O_(4)(g) iff 2NO_(2)(g) . At a fixed temperature, the volume of the container is halved. For this change, which of the following statements is true regarding the equilibrium constant K_(p) and degree of dissociation (alpha) of N_(2)O_(4) ?

The equilibrium constant can be expressed in terms of partial pressure as well as concentration. What is the relation between K_p and K_c for the reaction, N_2(g)+O_2(g) gives 2NO(g)?

2 mols of PCl_(5) were heated in a sealed 5L container to constant temperature. If the degree of dissociation of PCl_(5) at this temperature is 0.4, the K_(c) of the reaction PCl_(5)(g) iff PCl_(3)(g)+Cl_(2)(g) is very close to

A vessel of '1000 K' contains 'CO_2', with a pressure of '0.5 atm .' Some of the 'CO_2' converted into 'CO' on the addition of graphite. The value of 'K' if the total pressure at equilibrium is '0.8 atm'. is:
