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) Heats of combustion of graphite and hydrogen at 300 K are -400 kJmol^(-1) respectively. If on combustion, 1 g of glucose releases 15 kJ of energy. calculate the heat of formation of glucose at 300 K.
