The equation below represents a chemical reaction that produces a gas, 2Na(s) + 2H20(1) + 2NaOH(aq) + H2 (9) What is the theoretical yield in liters of H, gas if 5.00 g of Na are completely reacted and the H, gas is collected at STP? A 0.109 L B 2.44 L с 4.88 L 4.88 L D 5.09 L​

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
