Endothermic reactions, having `DeltaS = +ve` masy be spontaneous if

Assertion: A non-spontaneous endothermic reaction at room temperature may be spontaneous at high temperature. Reason: At high temperature TDeltaS becomes more than DeltaH .

For endothermic reaction Delta H value is-

Determine whether reactions With following DeltaH and DeltaS values are spontaneous or non spontaneous. State whether they are exothermic or endothermic. DeltaH =-110 kj and DeltaS = + 40JK-lmol-1 at 400 K

Determine whether reactions With following DeltaH and DeltaS values are spontaneous or non spontaneous. State whether they are exothermic or endothermic. DeltaH = + 40 kj and DeltaS =-120 JK-1 mol-1 at 250K

An endothermic reaction which may be non spontaneous at low temperature because of entropy factor becomes spontaneous at high temperature.

Assertion : Many endothermic reactions which are non- spontaneous on increasing the temperature. Reason : Endothermic reactions become spontaneous at high temperature if DeltaS is +ve and TDeltaS gt DeltaH .

Decrease in free energy of a reacting system indicates: an exothermic reaction an endothermic reaction a spontaneous reaction a slow reaction.

What is the sign of DeltaS for a spontaneous reaction ?
