In the incomplete reaction N2 + O2 --> 2NO K=0.01 originally in a 1L solution we have 0.4 mole of N2 and 0.1 mol of O2 and 0.08 mol of NO. If the volume of the equilibrium solution of N2, O2 and NO is decreased to 0.5L, shoulodn't the concentration of NO increase?

the answer is true. hope it .

there are two significant figures.

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
