Photosyntesis is a bio process by which planets make energy rich molecules from low energy molecules with the help of energy. From sunlight. The photosynthesis of glucose can be represented as : 6CO_(2)(g)+6H_(2)O(g)+hvrarrC_(6)H_(12)O(s)+60_(2)(g) Electrochemical oxidation of glucoses to CO_(2) and H_(2)O. which is the reverse of photosyhnthesis, is an impottaint reaction and it can be used in the construction of a fuel cell. In a fule cell, a working substance celled fule is electrochemiclly oxidised by O_(2) C_(6)H_(12)O_(6)+6HOrarr24_(e)^(-)+24H^(+)+6CO_(2) Calculate the approximate standard emf of this fuel cell at 27^(@)C if DeltaH^(@) and DeltaS^(@) of above photosynthesis reaction are -3xx10^(6)Jmol^(-1) and 200 JK^(-1)mol^(-1)respectively :
