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
Number of coulombs of current required to convert completely 1 mole of MnO4-ions in acid medium to one mole of Mn2+ions electrolytically is
In a 500ml flask,the degree of dissociation of PCl5 at equilibrium is 40% and the initial amount in 5 moles.The value of equilibrium constant in mol lit-1 for the decomposition of PCl5 is
