5 moles of `N_2` and 10 moles of `H_2` are made to react in one litre vessel. At equilibrium 4 moles of `NH_3` is formed. The value of `K_c` is

2 mole of H_(2) and "1 mole of "I_(2) are heated in a closed 1 litre vessel. At equilibrium, the vessel contains 0.5 mole HI. The degree of dissociation of H_(2) is

5 moles of SO_(2) and 5 moles of O_(2) are allowed to react to form SO_(3) in a closed vessel. At the equilibrium stage 60% of SO_(2) is used up. The total number of moles of SO_(2), O_(2) and SO_(3) in the vessel now is

A mixture of 2 moles of N_(2) and 8 moles of H_(2) are heated in a 2 lit vessel, till equilibrium is established. At equilibrium, 04 moles of N_(2) was present. The equilibrium concentration of H_(2) will be

1.0 mole of ethyl alcohol and 1.0 mole of acetic acid are mixed. At equilibrium, 0.666 mole of ester is formed. The value of equilibrium constant is

10 moles of each N_(2) and H_(2) are made to react in a closed chamber. At equilibrium 40% of H_(2) was left. The total moles in the chamber are :

28 g of N_2 and 6 g of H_2 were kept at 400 ^(@) C in 1 litre vessel , the equilibrium mixture contained 27.54 g of NH_3 The approximate value of K_c for the adove reaction can be ( in " mol"^(-2) L^(-2))

One mole of H_(2) and 2 moles of I_(2) are taken initially in a two litre vessel. The number of moles of H_(2) at equilibrium is 0.2. Then the number of moles of I_(2) and HI at equilibrium is

4 moles each of SO_(2) "and" O_(2) gases are allowed to react to form SO_(3) in a closed vessel. At equilibrium 25% of O_(2) is used up. The total number of moles of all the gases at equilibrium is

Three moles of PCl_(5) , three moles of PCl_(3) and two moles of Cl_(2) are taken in a closed vessel. If at equilibium, the vessel has 1.5 moles of PCl_(5) the number of moles of PCl_(3) present in it is
