Mechanisms for linking light reactions to the Calvin cycle do NOT include 1. Redox control of enzymes in the calvin cycle
2. pH changes in the stroma as a result of proton pumping by cytochrome b6f
3. Mg2 release from the thylakoid membranes 4
. Direct transfer of electrons from activated special chlorophyll molecules to enzymes in the Calvin cycle

the right answer is c i just did 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

answer; the numbers of valence electrons in the acetic acid molecule (ch3co2h) is 24;
