1.	The reaction quotient, Q is expresse as some as, that for equilibrium constant K.The value of Q for the given composition of a reaction mixture helps us to know whether the reaction will move forward or backward or remain in equlibrium. It helphs to pedict the effect of pressure on the direction of the gaseous reaction. In some reactions, addition of inert gas also favours either the formation of reactansts or products. The value of equlibrium constant of a reaction changes with change of temperture and the change is gives by van't Hoff equation, d ln K_(p)//dT=DeltaH^(@)//RT^(2) where enthalpy change, DeltaH^(@), is taken as constant in the small temperatue range. Which of the following will be correct
Answer» Plot of LN `K_(p)` VERSUS `1//T^(2)` will be linear with +ve slope Plot of ln `K_(p)` versus `1//T`will be linear with +ve slope Plot of ln `K_(p)` versus `1//T^(2)` will be linear with-ve slope Plot of ln `K_(p)` versus `1//T` will be linear with -ve slope SOLUTION :`(d lnK_(p))/(dT)=(DeltaH^(@))/(RT^(2))"GIVEN ln"K_(p)=(DeltaH^(@))/(RT)."Hence, polt of " ln K_(p)vs1//T` will be linear with slope `=-DeltaH^(@)//R.`
