1 mole of PCl5 is heated with 0.2 mole of chlorine in a one litre vessel till equilibrium is established. At equilibrium if 0.8 mole of chlorine in the vessel, the value of equilibrium constant for the dissociation of PCl5 is (in moles-lit-1)
The electrolytic conductance of 0.01 M solution of acetic acid is 0.000163 Scm-1 at 298k. The % of dissociation of acetic acid at 298K.Given Am0 of acetic acid =390.7 Scm-2/mole at 298K.
A(g)+2B(g)⇔2C(g)+D(g) was studied using an initial concentration of B which was 1.5 times that of A .But the equilibrium concentrations of A and B were found to be equal .Then Kc for the equilibrium
Dipole moment of HC1 = 1.03 D, HI = 0.38 D. Bond length of HC1 = 1.3 and HI = 1.6A .The ratio of fraction of an electric charge, δ, existing on each atom in HC1 and HI is
If the bond length and dipole moment of a diatomic molecule are 1.25 A and 1.0D respectively,what is the percent ionic character of the bond
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
