Using the following equations, determine Δ Δ H (in kJ) for the following reaction: C3H8(g) + 5O2(g) → → 3CO2(g) + 4H2O(g) 3C(s) + 4H2(g) → → C3H8(g), Δ Δ H = -103.8 kJ C(s) + O2(g) → → CO2(g), Δ Δ H = -393.5 kJ H2(g) + 1/2O2(g) → → H2O(g) , Δ Δ H = -241.8 kJ

metric time was an attempt to create a standard unit of time based off of 10, but it never took off an is not included in the metric system (si)

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
