Photosysthesis si a bio process by which plants make energy rich molecules from low energy molecules with the help of energy from sunlight . The photosysthesis of glucose can be represented as:
`6CO_(2(g))+ 6H_(2)O_(g) + hv rarr C_(5)H_(12)O_(6(s)) + 6O_(2)(g)..........(i)`
The energy of one mole of a photon of wave lenght is known as one Einstein.
Variation of emf of an electrochemical cell with temprature is known as the temperature coefficient of the cell .If `delta(DeltaG//deltaT)_(p)=-DeltaS`, calcualte the temperature coefficient fo the glucose fuel cell at `25^(@)`C from the data given in 3.7.

Text Solution

Verified by Experts

The correct Answer is:
`(d(-nFE))/(dT) =-DS implies nF((dE)/(dT)) = Deltas therefore (dE)/(dT) = 7.86 xx 10^(-5)`
