Detailed Solution

A) Value of Keq is affected by temperature - True ;Explanation ; Keq=KfKb;(Kf = rate constant of forward reaction, Kb = rate constant of backward reaction)Rate constant increases with increase in temperature; Increase in rate constant for exothermic reaction will be less than for an endothermic reaction.Let the forward reaction be exothermic reaction. So if temperature increases, Kf increases and Kb increases but increase in Kf is less than Kb∴Keq decreases with increase in temperature.Let the forward reaction be endothermic reaction. So if temperature increases, Kf and  increases but increase in Kf is more than KbKeq increases with increase in temperature.B) Equilibrium constant gives an idea about the extent of completion of reaction - True.Explanation-Greater Keq value indicates that the reaction goes almost to completion.K > 103 .... forward reaction is favouredK < 10-3 .... backward reaction is favouredK = 10-3-103…both forward and backward reactions are favoured appreciably.C) Equilibrium constant is affected by volume and pressure changes - false.Equilibrium constant is affected by temperature change and change in stoichiometry.
