The effect of temperature on equilibrium constant is expressed as (T_(2)gtT_(1)) log K_(2)//K_(1)=(-DeltaH)/(2.303)[(1)/(T_(2))-(1)/(T_(1))] . For endothermic, false statement is

Assertion : The equilibrium constant of an exothermic reaction decreases as temperature increases. Reason : log(K_(2)/K_(1))=(DeltaH)/(2.303R)(1/T_(1)-1/T_(2)) where T_(2) gt T_(1) . Since for an exothermic reaction DeltaH is -ve, it follows that K_(2)/K_(1) lt 1 or K_(2) lt K_(1) .
