Pick out the incorrect statement among the following
(I) Change in Gibb's function at constant temperature and pressure in a process envolving no non PV work is equal to ( - )
(II)For a reaction with as positive, as temperature is increased, Keq for the reaction increases necessarily
(III) Exothermic reactions have lesser tendency to go in forward direction at higher temperature
(IV) Decrease in Gibb's function at constant temperature and pressure is equal to non PV work done by system
