The molar ionic conductivities of NH4+ and OH- at infinite dilution are 72 and 198 ohm-1cm2mol-1 respectively.The molar conductance of a centinormal NH4OH solution at the same temperature is found to be 9 ohm-1cm2mol-1,The percentage dissociation of NH4OH at this concentration will be
One mole of A and 2 moles of B are allowed to react in a one lit flask. What is the value of Kc if at equilibrium,0.4 moles of C is formed in the reaction A+2B⇔C+2D
H3O++OH-→2H2O
The solubility of AgCl in NaCl solution is less than that in pure water,because
The equilibrium constant for the reaction H2(g)+I2(g)⇔2HI(g) is 81 at a certain temperature.If the concentrations of H2 and I2 are 3mole.lit each at equilibrium,the equilibrium concentration of HI is
consider the following reaction equilibrium N2(g)+3H2(g)⇔2NH3(g).Initially 1 mole of N2 and 3 moles of H2 are taken in a 2 litre flask.At equilibrium state if the number of moles of N2 is 0.6 what is the total number moles of all gases present in the flask at equilibrium
On passing a current through molten KCl 19.5g of K is deposited.The amount of aluminium deposited by the same quantity of electricity if passed through molten AlCl3 is
A quantity of PCl5(g) was heated in a 10 litre vessel at 2500C PCl5(g) ⇔PCl3(g)+Cl2(g) At equilibrium the vessel contains 0.1 mole of PCl5 0.2 mole of PCl3 and 0.2 mole of Cl2 .The equilibrium constant is
Three faradays of electricity are passed through molten Al2O3,aqueous solution of CuSO4 and molten NaCl taken in three different electrolytic cells.The amount of Al,Cu and Na deposited at cathodes will be in the ratio
