Use the reaction 2CO(g) + O2(g) 2CO2(g) for the following questions iv. a gas mixture contains 4.8 10–4 M CO and 3.5 10–2 M O2, and Keq = 3.58 10–4. What would the equilibrium concentration of CO2 be at these conditions?

v. If at another temperature the Keq = 8.28 1010, would the reaction favor product formation or reactants? Explain your answer.

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.

practical process described pest part of scientific investigation.

because practical knowledge is powerful then therotical knowledge.

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
