Leann is learning about chemical reactions. She wants to create a model of a chemical reaction, so she is examining the information that she should include. What are the different components that she should include in her model? Choose the three that apply. A. the kinds of atoms that form during a reaction
B. the kinds of molecules involved in the reaction
C. the kinds of elements that make up a molecule
D. whether the molecules are products or reactants
E. whether the products have more mass than the reactants

what are the statements

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
