In the reaction of Lithium and Fluorine, each Li atoms takes 1 electron from an F atom to form 1 mol of gaseous Li+F- ion pair. Due to their opposite charges, they attract each other with a net force of 6.735 x 10-12N. Calculate the amount of energy when one mole of Li+F- ion pairs is formed from the separated ions, given that n=7. The observed inter-nuclear distance in the gas phase between ions is 156 pm. (Use ε0= 8.85 x 1012 C2/N-m2).
Do not round off your answers from the start of the solution until the final answer.

During photosynthesis in a certain plant, eight photons of 670-nm wavelength can cause the following reaction: 6CO2 + 6H2O → C6H12O6 + 6O2During respiration, when the plant metabolizes sugar, the reverse reaction releases 4.9 eV of energy per CO2 molecule.
Determine the ratio of the energy released (respiration) to the energy absorbed (photosynthesis), a measure of photosynthetic efficiency.
