Why are the products of the light reaction of photosynthesis important? answers?

Answer : Light reactions are important in photosynthesis because

The light reaction provides the required amount of chemical energy in the form of ATP (Adenosine Tri phosphate) and NADPH (Nicotinamide Adenine Dinucleotide Phosphate) . After this reaction the chemical energy generated is later used to make glucose for performing the dark reactions of photosynthesis.

wher is the rest of the question

answer : (a) volume of the gas = 8.67 ×   l

                (b) second virial coefficient b = -1.21226 l/mole

solution :   given,     t = 300k

                                p = 20atm

                                z = 0.86

                                n = 8.2 mmoles = 8.2 × moles

                                r =   0.082 l atm/k/mol

        find,     (a) volume of gas   and (b) second virial coefficient b at 300k.

formula used :            

                          and            

(a)            

                    = \times 0.082\times 300}{20}[/tex]

                    = 8.67 ×   l

(b)      

                    = (0.00867-1) × 8.659

                    = - 8.5839 l/mole
