1.	Justify the following statements `:` (a)Reactions with `DeltaG^(@) lt 0`always have an equilibrium constant greater than 1. (b)Many thermodynamically enthalpy feasible reactions do not occur under ordinary conditions. (c ) At low temperature , enthalpy change dominates the `DeltaG` expression and at high temperatures, it is entropy whch dominatest the value of `DeltaG`.
Answer» (a)Aready discussed already (b) Under ordinary conditions, the average energy of the reactants may be less than threshold energy. They requiresome activation energy to initiate the reaction. (c )`DeltaG = DeltaH - T DeltaS`. At low temperature, `TDeltaS` is small . Hence,`DeltaH ` dominates. At high temperatures,`T DeltaS` is large, ie., `DeltaS` dominates the value of `DeltaG`.
