If decomposition of 1 mole of ethylene with a gas density of 0.215g/mL starts at 29 degree celcius and the temperature increases
stellarik [79]
We calculate first the initial pressure of the gas. 
                         P = nRT/V
                            = (0.215 g/mL)(1 mol/16 g)(0.0821 L.atm/mol K)(302K)
                             = 0.333 atm
Using the relationship between the pressure and temperature,
                       P1/T1 = P2/T2
Substituting the known values,
                        (0.333 atm) / (29 + 273) = P2/(950)
                                 P2 = 1.05 atm
