For an exothermic reaction in which the number of moles of reactants are more than the number of moles of products. In order to displace the reaction in the reverse direction, what are the favourable conditions 

For dissociation of PCl5 ,mole fraction of Cl2 at equilibrium is 0.3. The total pressure is 1.0 atmosphere. The partial pressure of PCl3 at equilibrium is –

In an equilibrium reaction for which Gº = 0, the equilibrium constant K should be equal to – 

When 120 g acetic acid is reacted with 138 g ethyl alcohol, the amount of alcohol consumed is 30% of its initial concentration. The number of moles of acetic acid at equilibrium are –

The oxidation of SO2 to SO3 by oxygen is an exothermic reaction. The yield of SO3 will be maximum if –

In Bodenstein experiment, one mol H2 and two mol I2 are taken initially in a one litre flask. If at equilibrium 0.5 mol H2 are present, the equilibrium concentrations of I2 and HI in mol l –1 are –

2.0 mol of PCl5 were introduced in a vessel of 5.0 L capacity at a particular temperature. At equilibrium, PCl5 was found to be 35% dissociated into PCl3 and Cl2 . The value of Kc for the reaction is -

When 8.1 ml of hydrogen and 9.3 ml of iodine vapour are heated to 444º, 13.5 ml of HI are produced. The equilibrium concentration for H2 and I2 respectively should be - 

A catalyst does not alter the equilibrium point.

For any reaction greater the value of equilibrium constant greater is the extent of completion of reaction.

The value of equilibrium constant does not depend upon pressure.
