Negative deviation occurs when the total vapour pressure is less than what it should be according to raoult's law. considering the same a and b components to form a non-ideal solution, it will show negative deviation from raoult's law only when: o a. pia p[ao] times x[a] and p[bi < pibo] x[bi as the total vapour pressure (p[ao] xia] + p[b0] xib]) is less than what it should be with respect to raoult's law. o b. the solute-solvent interaction is stronger than solute-solute and solvent-solvent interaction o c. the enthalpy of mixing is negative because stronger attractions are formed. o d. the volume of mixing is negative becasue stronger attractions have led to a contraction in volume o a and b only o a, b and c only all of the above

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.

hi my dude or dudette

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
